Bel's New DC/DC Converters Power Low Voltage Silicon From 5V Source


10A Converters Deliver Greater Than 94% Efficiency

Jersey City, NJ, April 5, 2002...The new V7PC-10B series of non-isolated step-down DC/DC converters is now available from Bel, a premier developer of magnetic-based solutions for networking and computing applications. Boasting an industry standard single-in-line package (SIP) while providing up to 10A of output current from a 5V source, modules may be ordered in a range of output voltages from 3.3V down to 1.0V. The 2.5V unit (V7PC-10B25S) delivers state-of-the-art efficiency of 92% at full load, whereas the 3.3V unit (V7PC-10B33S) delivers 94%. Their high-efficiency design, coupled with robust thermal management, allows Bel's newest devices to provide 10A of output current in the same footprint as many competitors' parts providing only 6A.

Utilizing less than one square inch of PCB real estate, this pre-tested and pre-qualified series is specifically engineered for designers working with minimal board space and charged with shortening time-to-market. The targeted applications of the modules include computers and peripherals, telecommunications, networking, test, and industrial automation equipment. Moreover, they provide an economical solution to powering low voltage silicon as units frequently cost 20% to 40% less than comparable products.

For placement behind either off-line switchers or isolated DC/DC converters, Bel's components feature overvoltage and short-circuit protection, remote on/off, along with fixed-frequency operation. Devices further operate to 70 C with no derating over a 4.5 to 5.5V input range. An optional remote sense pin is offered for applications demanding precision regulation of low output voltages.

Prices for Bel's V7PC-10B series of non-isolated DC/DC step-down converters are $9.75 each in quantities of 10K. Delivery is from 4 to 6 weeks, while samples are immediately available. Specifications are available on the company's web site.
