Cree, Inc. Introduces Its First Schottky Diodes
DURHAM, N.C. Cree, Inc. today introduced the first silicon carbide (SiC) Schottky diode chips to be offered by the company. The initial product family will consist of two products: a 600 Volt, 1 Amp device and a 600 Volt, 4 Amp device. The company is currently sampling devices and targeting to ramp production during the first quarter of fiscal 2002. Additional offerings are expected to be added to the product family over the next year.
Potential SiC Schottky diode applications include power conditioning for high frequency power supplies and power factor correction as well as for power conversion in motor controls. Presently up to 50% of the power loss in a typical power circuit is attributable to the switching speed of the silicon PIN diode. Because of the much faster switching speed of a SiC Schottky diode, it is anticipated that the switching loss associated with the diode can be virtually eliminated, resulting in an overall 4-7% reduction in the amount of power consumed by the circuit. This reduction in power consumption should allow for smaller heat sinks and switch requirements thus reducing the cost and size of the circuit.
Chuck Swoboda, President and Chief Executive Officer of Cree stated, ``Our focus and investment in R&D continues to expand our product portfolio by offering new devices that we believe are superior to existing silicon-based products presently available in the marketplace. These devices are state-of- the-art and enable Cree to deliver on the long-standing promise of silicon carbide power device capabilities.''
Also announced by Cree are power results demonstrated by Kansai Electric Power Co., Inc. (KEPCO) of Osaka, Japan. KEPCO recently presented power results using devices fabricated at Cree in our joint program at the International Symposium on Power Semiconductor Devices in Osaka, Japan where they demonstrated record results with a 6 kV MOSFET (metal-oxide-semiconductor field effect transistor) and a 5.5 kV JFET (junction field effect transistor) that had on-resistances that were 1/25th and 1/65th lower, respectively, than the theoretical limit for an equivalent silicon device. Additionally, high voltage SiC PIN diodes were demonstrated with blocking voltages up to 19 kV, a 50% increase over our previous record and almost double what is commercially available on silicon. KEPCO believes that these devices could lead to the development of circuits with much lower power losses than in silicon-based circuits.
North Carolina-based Cree, Inc. develops and manufactures semiconductor materials and devices based on silicon carbide (SiC), gallium nitride (GaN) and related compounds. The company's products include blue and green LEDs, RF power transistors for use in wireless infrastructure applications, SiC crystals used in the production of unique gemstones and SiC wafers sold for use in research and development. Cree has new product initiatives based on its experience in SiC and GaN-based semiconductors, including blue laser diodes for optical storage applications, high frequency microwave devices for radar and other communications systems, and power devices for power conditioning and switching.

This press release contains forward-looking statements involving risks and uncertainties that may cause actual results to differ materially from those indicated. Actual results may differ materially due to a number of factors, including the risk we may encounter delays or other difficulties in ramping up production of new products; the risk the company will be unable to manufacture the products with sufficiently low cost to offer them at competitive prices or with acceptable margins; the rapid development of new technology and competing products that may impair demand; risks associated with the commercial release of new products under development, including the possibility we will be unable to develop and manufacture commercially viable versions of such products; the potential lack of customer acceptance of new products; and other factors discussed in Cree's filings with the Securities and Exchange Commission, including its report on Form 10-K for the year ended June 25, 2000 and subsequent quarterly reports.=========================================================================================================

Posted : 18 Jul 2001
Philips Semiconductors, a division of Royal Philips Electronics, (NYSE:PHG, AEX:PHI), has launched a highly efficient new 600V fully integrated half-bridge driver IC for liquid crystal display (LCD) backlighting. Manufactured in the company's advanced 650V BCD power-logic process, the UBA2070 can be connected directly to rectified AC line supplies without the need for a separate up/down convertor.
Philips Semiconductors has a world-class reputation for driving fluorescent lamps, such as TL and CFL types, and the high voltage technology and expertise developed for these lamp systems have now been used to extend the company's product range to include cold cathode fluorescent lamps (CCFL).
The UBA2070 high voltage, monolithic CCFL driver IC has a typical input voltage range of 12V to 600V DC. This high-voltage input capability provides an optimum system solution for CCFLs in a wide range of products that use LCD screens. These include laptop PCs, personal digital assistants and satellite navigation systems. Used with a high voltage input, the UBA2070 runs at efficiency levels in excess of 90 per cent and is ideally suited for high-power multiple-lamp systems such as those used in LCD monitors.
"The unique blend of features, coupled with the low number of external components required, makes the UBA2070 the most efficient solution currently available on the market today," said Latif Gau, product marketing manager for lighting ICs at Philips Semiconductors.
¡@
The UBA2070 offers an unrivalled range of features, including adaptive non-overlap time control, integrated high voltage level-shifting functions, a power-down function and capacitive mode protection. Also including lamp failure detection, short circuit detection and a dimming feature, it provides the highest level of integration available for fluorescent lamp driving. In particular, by dimming down the maximum light output by 95 per cent, the UBA2070 offers LCD monitor designers greater scope for enhancing the user interface.
The UBA2070 also offers system designers more freedom with respect to supply voltage choice, thus enabling a more flexible system architecture in combination with the power supply. Its outputs drive two discrete external power MOSFETS in a half bridge configuration.
¡@
Two versions of the chip are available - the UBA2070T (SO16), which is housed in a small outline package with 16 leads, and the UBA2070P (DIP16) which is a dual-in-line package, also with 16 leads.

Abstrate: SALEM, Ore.--Mitsubishi Silicon America today announced a new wafer substrate product that features N/N+ epitaxial silicon for reduced junction leakage and improved device reliability in power ICs and bipolar devices.
"We designed this material to meet the specific needs of power MOSFET and bipolar device makers," said Fritz Kirscht, who led MSA's engineering team in developing the product over the past two years. "Specifically, we addressed the need to reduce device current leakage, stabilize device yields in contaminated lines, improve device reliability, and enhance performance at lower levels of resistivity."
The epi substrate wafers, called iGEM, are currently available with diameters of 150 mm (6 inches). The wafers are a result of Mitsubishi Silicon America's experience in heavily doped, low resistivity wafers, according to managers. The U.S. subsidiary of Mitsubishi Materials Corp. said tests by customers have demonstrated reduced junction leakage and more robust gettering. Theenhanced gettering reduces variation in critical device properties, providing greater device reliability, said the company.
Other potential advantages currently being evaluated include reduced slip and bow, resulting in improved mechanical stability of the wafer, said MSA in Salem.
"We see the opportunity for customers to eventually lower their total cost of ownership using iGEM," said George Robillard, vice president of marketing at Mitsubishi Silicon America. "The engineered improvements in iGEM complement conventional techniques that increase gettering in low resistivity wafers -- techniques like thin films and backside damage."
According to MSA, the switch from conventionally gettered, low-resistivity wafers to iGEM epi substrates requires little, if any change in semiconductor fab processes.

¡@
NUREMBERG, Germany -- Infineon Technologies AG today launched a series of second-generation integrated multi-chip power devices that combine a power MOSFET--fabricated in the company's CoolMOS technology--with a fixed frequent pulse width modulator (PWM) control chip. The two chips are combined inside an 8-pin plastic DIP.
"Compared to components produced in standard power MOSFET technology, devices in CoolMOS technology reduce the area-specific resistance RDS (on) by a factor of five," said Reinhard Ploss, head of Infineon's Automotive & Industrial group. "It is Infineon's goal to offer intelligent power management and supply solutions, which substitute heatsinks in the long term."
The new CoolSet F2 series was introduced by Munich-based Infineon at the PCIM 2001 trade show in Nuremberg. The series is aimed at an extremely wide range of applications, including battery chargers for mobile phones and portable systems, printers and fax machines, DVD players, set-top boxes, and auxiliary power supplies for PCs, washing machines and other equipment.
CoolSET F2 products are available with drain-source breakdown voltages of both 650 and 800 volts, for output currents of 1 to 3 A. The primary voltage ranges from 85 to 265 V, said Infineon.
The CoolSET F2 family derivatives ICE 2A165, ICE 2A265, ICE 2A365, and ICE 2A280 are available in sample quantities. In quantities of 10,000, the component ICE 2A365 (47-W maximum output power at 85 V--265 V primary voltage) is priced at 0.95 euro each (or about 82 cents).

Announces High Voltage Chip Integrating 15W Offline Power Supply
L6590 includes 700V DMOS transistor plus control circuits for flyback, boost or
forward AC-DC converters
Geneva,
May 23, 2001 - Designed to simplify offline power supplies up to 15W, the L6590
<http://us.st.com/stonline/books/pdf/docs/5751.pdf>
Fully Integrated Power Supply chip from STMicroelectronics (NYSE: STM)
integrates a 700V power MOSFET switch, plus all of the control circuits needed
to build a converter using flyback, boost or forward topologies. The device
operates over the universal input voltage range of 85VAC to 265VAC and also with
DC inputs, making it a flexible solution for consumer applications in all world
markets.
An
on-chip 65kHz oscillator eliminates the need for external oscillator components
and a non-dissipative internal startup circuit guarantees high efficiency at
light load and also further reduces the external parts count. Standby operating
mode ensures high efficiency at light loads (Pin<200mW @ Po=0W) meeting the
tightest regulations concerning standby operation. A brownout function prevents
spurious turn on at power down and protects against input line undervoltage. In
addition, an on-chip error amplifier improves primary regulation, avoiding the
cost of an external optocoupler and op-amp feedback network.
Typical
applications of the L6590 include wall plug power supplies, AC-DC adapters,
auxiliary supplies for CRTs, LCD monitors, desktop PCs and servers, fax machines
and laser printers.
Three
package versions are available. The L6590D is assembled in a 16-lead
Small-Outline package (SO-16W) and provides both the brownout and error
amplifier connections. Types L6590N and L6590AN are both assembled in 8-lead DIP
packages and exclude either the error amplifier (L6590AN) or the brownout
function (L6590N).
Design
support for the L6590 includes an evaluation package - order code EVAL6590N
-that contains samples, an evaluation board and PC software, which simulates the
application function. This software assists in the selection of external
components and simulates overall application performance. An application note is
available from www.st.com.
The L6590 is fabricated using ST's proprietary BCD-Offline technology, which allows the integration of 700V power devices and control circuits on the same chip. This technology is used in a variety of applications including offline power supplies and energy-saving electronic lamp ballasts. BCD-offline is a high voltage implementation of ST's bipolar-CMOS-DMOS (BCD) technology family that is applied in a broad range of smart power applications ranging from simple motor drivers to complex smart power subsystems with embedded microcontrollers.

Low-Cost,
Dual-Output SLIC Power Supply Uses Standard Transformer
SUNNYVALE,
CA-May 23, 2001-Maxim Integrated Products introduces the MAX1856 power supply
IC, which generates a low audio noise "talk battery" supply at -24V
and a stiff "ring battery" supply at -72V for voice-enabled broadband
consumer premises equipment (CPE) applications such as VoDSL modems, VoPacket
cable modems, LMDS, MMDS, WLL, and FTTH. To minimize total cost, the MAX1856
controller uses a single external N-channel MOSFET, a low-cost standard
transformer available from multiple vendors, and few additional low-cost
components. Its wide 3V to 28V input voltage range allows operation with a
low-cost, unregulated wall adapter output.
The
MAX1856 employs flyback topology to reduce input ripple current, which permits
use of a smaller, lower cost input capacitor. It also employs digital soft-start
to permit a smaller input capacitor. Its switching frequency can be set from
100kHz to 500kHz, or synchronized to an external clock signal in order to reduce
switching noise.
The
output voltages are set by selecting the appropriate transformer turns ratio and
feedback resistor values, allowing flexibility to work with many different SLIC
chip sets. The separate split feedback scheme provides good cross regulation on
both output signals and provides a stiff supply that reduces ring trip transient
noise.
The
MAX1856EUB comes in a 10-pin £gMAX package and is specified for the
extended-industrial temperature range (-40¢XC to +85¢XC). Prices start at $1.57
(1000-up, FOB USA). The MAX1856EVKIT (evaluation kit) is available to speed
designs.

Semiconductor rolls out highly integrated multiphase buck controllers
Posted
: 28 May 2001
Claimed
to be the industry's most highly integrated multiphase buck controller ICs for
powering high-performance microprocessors, the CS5301 and CS5332 meet the Vcore
power requirements for Intel's Pentium 4 and AMD Athlon processors.
The
CS5301 is a three-phase step-down controller that employs the company's
proprietary multi-phase control architecture, known as Enhanced V2, to guarantee
balanced load current distribution, ensure fast transient response and provide
high performance. Its three-phase switching topology reduces ripple on the input
and output.
The
CS5332 is a two-phase buck controller with four on-board gate drivers and
identical control functionality. Like the CS5301, it also runs from either 5V or
12V supplies and is specified for operation between 200kHz and 800kHz.
Both
ensure fail-safe protection from overvoltage and overcurrent conditions, and
offer direct (single-pin enabled) on/off control. They also feature loss-less
current sensing, adjustable output voltage positioning and hiccup-mode current
limiting.
The CS5332 and CS5301 are housed in 28-lead and 32-lead SOICs and priced at $4.17 and $4.71, in 1,000 pieces, respectively.

Microsemi,
Cree team up to commercialize SiC Schottky diodes
Abstract : IRVINE, Calif.--Microsemi
Corp. and Cree Inc. today announced an alliance to develop and commercialize new
silicon-carbide (SiC) Schottky diodes for a wide range of high-volume power chip
applications.
ºKn¡GMicrosemi
Corp.«Å¥¬»P²{¦³ºÒ¤Æª¿(SiC)´¹¤ù»P½U´¹¤ù³Ì¥Dnªº¨ÑÀ³°ÓCREEÁp¦X¡A±Nµo®i°Ó·~¤Æ¥Í²£ºÒ¤Æª¿¿½¯S°ò(schottky)¤G·¥Å餧§Þ³N¡CMicrosemit³d°ªÀ£¤¸¥óªº¥]¸Ë§Þ³N¡ACreet³d½U´¹¤ù»s§@¡C
SiC
material and processes are capable of handling high voltage in ultra-high power
densities, said the two companies. Microsemi in Irvine and Cree in Durham, N.C.,
said they will cooperate in launching a new series of Schottky products under
the alliance.
The
SiC-based devices will be aimed at such applications as switching power
supplies, down-hole drilling systems, telecommunications rectifiers, and
charging circuits in implantable cardioverter defibrillators, according to two
companies.
Under
the terms of a development agreement, Microsemi will provide packaging,
application, and market channel expertise, while Cree supplies SiC chips for use
as high-power and high-voltage Schottkys.
Until
now, Microsemi said it has relied on university R&D groups to try to develop
SiC products for commercialization. This new agreement is expected to allow
Microsemi to accelerate its SiC program by relying on Cree's SiC manufacturing
know-how, bypassing university laboratories.
"We
have been very successful in identifying potential commercial applications for
SiC Schottkys, which range from energy conscious cardioverter defibrillators to
base station power supplies," said Manuel Lynch, vice president of
marketing and business development for Microsemi. "We wanted to move from
laboratory scale development to full scale production as we continue our
strategy of commercializing SiC.
"Cree
provides us with SiC Schottky expertise and is a formidable partner to help
launch these products for high-volume applications," he added.
The
joint development agreement will combine the use of Microsemi's patented
Powermite line of packages with Cree's proprietary SiC Schottky diodes.
Microsemi said its Powermite package can handle up to four times the power of
equivalently sized packages.
"By
combining Cree's expertise in SiC chip technology with Microsemi's high-power
packaging knowledge, we believe this relationship will prove beneficial in
developing SiC Schottky devices for high-volume applications and enable initial
penetration into the power device market," Chuck Swoboda, president and
chief operating officer of Durham-based Cree.

DURHAM, N.C. -- Cree Inc. here today announced availability of 3-inch diameter n-type 4H silicon-carbide (SiC) wafer substrates for production of radio-frequency (RF) and microwave devices.
Compared to existing 2-inch wafers, the new 3-inch diameter substrates more than double the available area for devices, said Cree, which believes it is the industry's only volume producer of single-crystal 3-inch SiC wafers.
Cree also today announced it has demonstrated 3-inch semi-insulating 4H SiC substrates. The company said larger semi-insulating SiC substrates will allow for cost-effective scaling of RF and microwave products in commercial production.
About 18 months ago, Cree introduced 3-inch n-type 6H SiC wafers for volume production of optoelectronics (see Oct. 8 story <http://www.siliconstrategies.com/story/OEG19991008S0002>).

The company said it was using a proprietary process to achieve 200 million cell-per-square-inch density. General Semiconductor said the new technology will be used to offer smaller power devices for cellular phones, notebook computers, and other portable electronics products.
The technology was called a breakthrough in power MOSFETs by Ronald A. Ostertag, chairman and CEO of the Long Island, N.Y.-based semiconductor company. "Our continued investment in our proprietary trench technology allows us to provide more efficient devices in smaller packages, which helps extend battery life in today's portable and wireless devices," he said.
The latest generation of the company's GENFET technology uses a 0.35-micron trench process to create the power MOSFET devices. General Semiconductor said the technology results in a specific RDS(on) of 0.41 milliohm per centimeter squared for a 30-volt P-channel device. The company said this was a 40% improvement over today's 49 million cell-per-square-inch technology.
General Semiconductor also said the new technology provides an improvement in the "on-resistance times gate charge." This specification is improved 60%, resulting in more efficient devices with significantly reduced energy losses, according to the company.
Initial samples of the new MOSFETs are expected to b available by the end of the second quarter. The products will be housed in 6-leaded SOT-23 and SOT-363 packages. Full production is slated to begin this summer

Internal series gate resistor (min 4.5 ohm) for easier paralleling
Ultra-low on resistance RDS(on)=0.0063 ohm, VGS=10V
April 10th, 2001 - San Jose, Calif.- The new FDB06AN08A1 UltraFETR Trench MOSFET from Fairchild Semiconductor International (NYSE: FCS), is designed for high-current starter/alternator, electronic power steering, electric braking, valve timing and other 42V automotive battery applications requiring full device capability at low gate drive voltages. Employing Fairchild's patented, advanced trench topology, the FDB06AN08A1 die is more than 20% smaller than those of competing technologies. This is particularly significant in the starter/alternator application, where of a large number of devices must be paralleled to accommodate starting currents of up to 1500A.
As mechanical systems are replaced with electronics, the increase in automobile power requirements has prompted the transition from the traditional 12V to a 42V battery to limit current requirements and control wire size and cost. This new 75V MOSFET is designed specifically for these systems that will begin to appear in new car models as early as 2003.
The FDB06AN08A1 N-Channel trench MOSFET features ultra-low RDS(on) (6.3 milliohm, max. at room temperature), 75V breakdown voltage, 175¢XC maximum junction temperature, an internal gate resistor and unclamped inductive surge (UIS) capability for single (1200mJ @ 75A) and repetitive pulses. Additionally, the die size of the FDB06AN08A1 leaves a substantial amount of D2-Pak (TO263) space available, allowing for die size flexibility and the potential to further lower the RDS(on) for the same package size.
The FDB06AN08A1 was developed and is manufactured at the Mountaintop, Pennsylvania* location, long recognized by industry observers for its technical leadership in power discretes for the automotive industry.

Offerings Provide Optimal Power Management Solutions for Computer-Based Systems
Posted
: April 4, 2001
Offering
the best mix of performance, price and functionality, National Semiconductor
Corporation (NYSE: NSM) today announced two highly integrated power management
controllers for today's complex embedded computer applications. These products
offer a complete power supply for any microprocessor, FPGA or DSP-based system
in one compact device. National's new high-efficiency synchronous step-down
regulator controllers have multiple outputs that can power notebook computers,
networking equipment, internet appliances, set-top boxes, graphics cards
including DDR memory, and industrial computer boards.
The
LM2633 and LM2645 combine all the blocks needed to create a PCB-level power
supply that can operate over an input range of 4.5V to 30V with maximum
efficiency. With their wide input voltage range, 10µA shutdown current, and
superior performance, these controllers meet the needs of portable and
line-powered systems.
"Multiple
IC process technologies dictate more and varied power sources in computer-based
system design," said John Perzow, National's business marketing manager for
power management products. "National is the only company that combines this
level of functionality and performance into one competitively-priced
package."
The
LM2633 combines two switching controllers and a linear controller. The LM2645
combines all the features of the LM2633 plus a 3.3V/50mA linear regulator. The
synchronous switching controllers can operate out of phase, thereby decreasing
the input peak current. This
technique results in significant cost savings by reducing the number of

The
Si91860DY, Si9912 and Si9913 are designed for power-conversion applications in
notebook and desktop computers.
The
Si91860DY regulates power for network interface cards, PCMCIA cards and PCI
interface cards. It combines an ultra-low supply current that reduces power
consumption with a highly integrated design that requires only four external
components for a complete application circuit. It provides peak output current
of 600mA (min.), and is capable of carrying at least 400mA continuous-load
current.
The
Si9912 and Si9913 half-bridge MOSFET drivers offload power MOSFET drive
requirements from the controller IC, increasing system design flexibility in
desktop and notebook computers, as well as computer peripherals and consumer
electronic products. They offer an extended input voltage range (4.5V to 30V),
with supply voltage ranging from 4.5V to 5.5V. Housed in 8-pin SOIC, both
devices integrate drivers capable of switching a 3nF load with a 60ns
propagation delay and 25ns transition time. They also offer a 1A drive current
that supports switching frequencies up to 1MHz.

April
11, 2001 (TOKYO)Toshiba America Electronic Components Inc. said it will set up a
company in San Jose, Calif., to develop microcontrollers incorporating the TX79
microprocessor..
The
TX79 is the CPU core in the EmotionEngine, the microprocessor jointly developed
by Toshiba and Sony Computer Entertainment Inc. for the PlayStation2 video game
machine.
The
new company, ArTile Microsystems Inc., will develop microcontrollers
incorporating TX79 for diverse applications other than video game machine, such
as networking appliances, digital set-top boxes, digital TVs and multimedia
appliances. It will be founded with 30 employees, and will have a staff of 200
in 2004.
TAEC
is spinning off its San Jose-based microprocessor engineering division as a
wholly-owned subsidiary. A TAEC spokesperson said, "Strengthening resources
to develop microcontrollers is indispensable for the expansion of the system LSI
business. It is better to found a new company to get excellent human resources
and give them better incentives."
ArTile
plans to achieve sales of US$250 million by 2004.
TEAC
is the North American marketing and sales arm of Toshiba Semiconductor Company
and Toshiba Display Devices and Components Company.

El
Segundo, Calif. - International Rectifier's 30-, 60- 100- and 200-volt p-channel
MOSFETs in the R5 Rad-Hard series claim high radiation hardness against total
ionizing doses and high immunity to single-event effects. For heavy ions, there
is no derating breakdown of voltage for gate thresholds up to 8 or 15 V
(depending on the ions' linear-energy transfer rate).
"These
devices are well suited for systems that must survive penetrating gamma rays and
neutron fluence from nuclear detonation," said Richard Southwell, marketing
manager for the company's Hi-Rel Components Group.
The
devices are said to be immune to high-energy particles and are hardened against
single-event gate rupture and single-event burnout. A total-dose rating of 1
Mrad allows designers to extend equipment lifetime up to 10 times over current
designs using 100-krad devices.

MOSFETs start at $200 each in lots of 1,000

The
TinySwitch-II family of energy-efficient, low-power, offline switcher ICs offers
an increased output power capability of up to 23W (15W with a universal input).
This monolithic IC family integrates a high-voltage power MOSFET, oscillator and
control circuitry into a single CMOS chip.
Built-in
features include auto-restart for short-circuit and open-loop fault protection,
frequency jittering for low EMI filtering cost, current limit and thermal
protection, programmable line undervoltage-detection, which prevents power
on/off glitches, circuitry to eliminate audible transformer noise, and very
tight tolerances with negligible temperature variation on key parameters. The
132kHz internal switching frequency reduces transformer size and allows the use
of lower-cost EF12.6 or EE13 cores.
The
switcher ICs employ the company's EcoSmart technology, which reduces energy
consumption, especially in standby and no-load conditions. Applications are in
low-power adapters for portable equipment, such as cell phones, PDAs, digital
cameras, external computer peripherals and power tools, and standby power
supplies for PCs and A/V devices.
In
1,000-piece quantities, pricing ranges from 74 cents each for the 5.5W TNY264P
in an 8-pin PDIP, to $1.09 each for the 23W TNY268G in an 8-pin surface-mount
package.
