Offering optimum efficiency and power density, the EQW010/020/030/040 series eighth-brick power modules are targeted at a broad range of communications equipment OEMs and can be used in powering distributed power and intermediate bus architectures as well as the latest integrated circuits or microprocessors.

DALLAS – (Dec. 8, 2005) -- Tyco Electronics Power Systems, Inc. today announced the release of its EQW010-040 series DC-DC converters, an extensive line of new generation, eighth brick, DC-DC power modules designed for regulated single output voltages ranging from 1.0Vdc to 12Vdc. The EQW series delivers up to 10A at 12Vout, 20A at 5V, 30A at 3.3V, 35A at 2.5V and 40A of output current for 1.8V and lower output voltages. These converters are suited for use in distributed power architectures, wireless networks, access and optical network equipment, enterprise networks for powering the latest generation ICs (DSP, FPGA, ASIC), and microprocessor powered applications.

EQW010-040 Series converters operate over a wide input voltage range of 36 to 75 Vdc, providing a single, precisely regulated output with full load efficiency of 92% at 3.3V output. This high efficiency converter series employs half-bridge conversion topology with highly optimized synchronous rectification and incorporates innovative edge-plating and packaging techniques to deliver superior thermal performance. Built-in filtering for both input and output minimizes the need for external filtering.

The EQW010-040 series is rated for wide operating temperature range of -40°C to - 85°C in an industry standard eighth-brick package of 57.9 mm x 22.9 mm x 8.5 mm (2.28 in. x 0.90 in. x 0.335 in.). Standard features include: remote on/off, remote sense, monotonic start-up under pre-bias conditions, zero reverse current during start-up and shutdown, over-temperature protection, input under/overvoltage protection, and output overcurrent/voltage protection. Surface mount interconnect and a base plate for superior thermal performance are available as options. The converters are designed to be fully compliant to RoHS EU Directive 2002/95/EC.

“I am excited about the introduction of this extensive line of EQW010-040 series converters,” said Sabi Varma, Vice President, Marketing and R&D at Tyco Electronics Power Systems, Inc. “We are committed to developing a full set of products that will deliver high power and exceptional performance to our customers.”

Each EQW010-040 module is priced at $38.20 for 1,000 units. Samples are available now. For further information, visit http://www.power.tycoelectronics.com or call +1 800 526 7819.
