Discrete Power Semiconductor Supplier Eyes SiC Diodes
Aiming to tap the benefits of zero recovery current and negligible switching losses with high temperature capability of silicon carbide (SiC)-based Schottky diodes, discrete power semiconductor supplier Advanced Power Technology (APT) has inked a licensing deal with Cree Inc. Under this agreement, APT will purchase Cree’s SiC zero-recovery Schottky diode dies, and produce packaged devices and modules under its own brand name.Using alternative packaging and innovative engineering, APT intends to address market segments not served by Cree. In addition, it will explore military, industrial, communications, semiconductor equipment, and medical applications for its SiC Schottky diodes and other designs created using these high-performance diodes. According to Glenn Wright, APT’s vice president of marketing and business development, APT intends to explore applications where low losses are critical and cost is warranted. This marks APT’s first offerings in SiC, said Wright.
In addition to standard plastic packages, the SiC diodes will be available in hermetic and high-performance packages. The plastic packages will be assembled in the Philippines, while the hermetic and advanced packages will be produced in the company’s facilities in Bend, Ore., and Bordeaux, France. APT will use its expertise in high-power semiconductor manufacturing to offer multidie parallel discrete devices in TO-220, TO-247, D2, D3, and SOT-227 packages, as well as hermetic packages with and without military screening. The dual-die packages will offer common cathode configuration. Furthermore, the supplier will offer the latest generations of MOSFETs and IGBTs built in combination with the SiC Schottky diodes in both boost and buck configurations. Power modules and other custom designs using the SiC zero recovery Schottky diodes will also be offered.
All SiC-based diodes in plastic packages will be rated at 175°C, while hermetic and high-performance packages will be rated at higher temperatures. Due to higher band gap property, these devices will offer extremely low leakage at elevated temperature. Other features include high thermal conductivity, faster switching speed compared to silicon diodes, and 600V to 1200V breakdown capability.
APT is already in sampling mode of 6A and 10A SiC Schottky diodes in plastic packages with plans to take these into production in the fourth quarter. For more information, visit www.advancedpower.com.

Maxim Integrated Products’ new MAX4411B headphone amplifier combines the patented stereo DirectDrive technology with a fixed-gain (-2V/V) configuration. This combination eliminates both the bulky dc-blocking capacitors and the external-gain setting resistors. The result is a low-cost, ultracompact headphone amp requiring very few external components and making it ideal for compact, portable equipment with audio playback.DirectDrive generates a ground-referenced output from a single 1.8V to 3.6V supply, which unlike competing solutions, doesn’t require a mid-rail dc bias voltage to be applied to the headphone jack ground pin. This doubles the dynamic range of the output swing and simplifies end-product design and reliability.
The MAX4411B has a fixed gain of -2V/V, produces 80MW per channel into a 16Ω load, and has very low 0.003% THD + N. A high 86 dB PSRR at 217 Hz allows direct operation from noisy supplies without additional conditioning. Independent left/right, low-power shutdown controls optimize power savings in mixed mode mono/stereo applications. In addition to minimizing size, the elimination of dc-blocking capacitors improves the amplifier's low-frequency response, allowing full-range audio reproduction. This is especially important for music and video playback. Comprehensive click-and-pop reduction circuitry ensures fast turn on/turn off times without audible glitches. The outputs include ±8kV ESD protection.

IEEE Ratifies PoE Standard; Interoperability Tests to Begin
Finally, years of work have paid off. Last month, the Institute of Electrical and Electronic Engineers (IEEE) ratified the Power over Ethernet (PoE) standard 802.3af-2003, which defines the specifications to deliver power over standard Ethernet cables. Approved by the IEEE Standards board on June 12, 2003, it’s expected to be published this month."The 802.3af standard will provide the first global standard for power," said Steve Carlson, chair of the 802.3af Task Force. "Thousands of new and innovative products will emerge to take advantage of having the proven robustness and reliability of Ethernet along with power on the same connector. In 10 years, no one will be able to remember when Ethernet ports didn't supply power."
According to Richard Webb, market analyst at Infonetics Research, "The 802.3af standard provides a stable basis from which vendors can continue to reduce the cost of installing and upgrading network devices; this can be a hidden cost in the deployment and scaling-up of wireless LANs and VoIP in particular, and so improves the investment case for both these technologies.
"The standard ratification will add extra impetus to the current trend amongst silicon vendors to design chipsets for laptops and portables that require low power consumption below the 12.95W prescribed in the PoE standard," said Amir Lehr, vice president, business development and strategic planning at PowerDsine. "As these devices become less power-hungry and PoE becomes the standard in most corporate IT environments, there will no longer be a need for business people to carry a variety of different plugs when traveling. Instead, the RJ45 jack will become the universal power jack. I confidently predict that in the next five years, more than 75% of enterprise network devices will be able to be powered by Ethernet."
Meanwhile, based on the new standard, major proponents like PowerDsine, Linear Technology, Maxim Integrated Products, and Texas Instruments continue to release products for this application. Others such as Intersil and Micrel are in the development mode. More are expected to join this fray. Consequently, in an effort to improve performance of PoE products supporting the new IEEE 802.3af standard, the University of New Hampshire’s InterOperability Laboratory (UNH-IOL) announced that multi-vendor PoE testing will be held August 4-8 at their facility in Durham, N.H. Member companies of the PoE consortium expected to participate include 3Com, Extreme Networks, Nortel Networks, PowerDsine, and Texas Instruments.
This PoE Group Test Period gives participating vendors the opportunity to test their PoE equipment in a small, neutral setting. Problems discovered during testing can be repaired immediately, rather than after products have been released to market. Providing interoperability and parametric testing, the UNH-IOL offers valuable feedback to vendors and the chance to examine interoperability with other implementations. The testing also allows UNH-IOL student engineers the opportunity to apply their knowledge and interact with the new technology.
According to Gerard Nadeau, manager of the UNH-IOL's PoE consortium, "The focus of our testing will be interoperability. We will also verify that power-sourcing equipment (PSE) is performing detection and powered devices (PD) are providing the proper signature. This event supports our member-based weekly testing of PoE products, utilizing tests from the IEEE 802.3af standard and those developed by our laboratory."
"Interoperability testing at the UNH-IOL is extremely valuable as the new PoE standard becomes more widely adopted with customers," said Rich Valley, vice president of TI's system power management group. "Through its relationships with the IOL and members of the PoE consortium, TI is enhancing its position to deliver advanced PoE-compliant power management solutions to our customers that have been tested and are fully interoperable."
Members can schedule individual testing at the laboratory at any time between scheduled multi-vendor group test periods. The UNH-IOL encourages vendors to conduct such testing through its provision of a neutral, multi-vendor test environment.

PWM Controller
Linear Technology’s LT1950 is a Pulse Width Modulator (PWM) controller with a sophisticated control mechanism to protect, simplify, and reduce the size of isolated/non-isolated 15W to 500W power supplies with 24V and 48V input supply rails. It features an adaptive maximum duty cycle clamp circuit to prevent transformer saturation and to protect the MOSFET from catastrophic failures. This feature reduces the transformer size by as much as 50%. Moreover, adjustable current slope compensation allows optimization of transient response with a minimum number of output capacitors.The LT1950's adaptive maximum duty cycle clamp follows the input voltage so that load and line transients do not cause excessive flux swing in the transformer. Without this feature, designers must use an oversized transformer, larger MOSFETs and extensive filtering. With its adjustable undervoltage lockout (UVLO), the LT1950 can be easily customized to operate with a wide range of input supplies. The operating frequency is adjustable with a resistor from 100kHz to 500kHz. The IC is synchronizable to an external clock while a precision internal reference guarantees an accurate output voltage. It’s packaged in a 16-lead SSOP.

Demand Increases for ‹5kVA UPS Products
In the recently released multi-volume study entitled "The 2002 Power Protection Market Intelligence Program," Venture Development Corp. (VDC) concluded in its North American Demand Analysis that the ‹5kVA UPS market is poised for extensive transition over the next five years. Global consumption of battery-powered uninterruptible power supplies (UPS) of all ranges is expected to increase at a relatively modest compound annual growth rate (CAGR) of 2.95% through 2006. Within the highly competitive North American ‹5kVA market, this growth should be driven primarily by consumer requirements for improved battery performance and an expanding set of applications for the following reasons:- End users do not have strong preferences towards specific brands. They do not draw associations to particular brands based on quality, service, price, or otherwise.
- Business segments did not show strong differences among various UPS product features or specifications. Most UPS systems were similar in offerings and had little variation for end users to choose from as a result.
- Growth in multiple applications for UPS systems across new segments will allow for various features and specifications to become more and less important. The uses for UPS systems across new applications such as entertainment will provide for more specific market segmentation and specialization by the vendors.
- Standardization of product features and specifications, and the subsequent expectations of end users will demand new and improved product performance in areas such as battery back-up time and physical dimensions.
