VPT Adds 15 Amp Point of Load DC-DC Converter to Space Family of Power Conversion Products VPT is the only manufacturer to now offer two point of load converters that are MIL-PRF-38534 Class H and Class K Qualified, 100K rad hard, and available off-the-shelf

BLACKSBURG, Va., May 8, 2012 /PRNewswire/ -- VPT, Inc., a HEICO company (NYSE: HEI.A) (NYSE: HEI), announced today the availability of a new point of load power converter designed and manufactured for use in the extreme environment of space. The new SVGA0515 Series point of load DC-DC converter is now qualified to MIL-PRF-38534 Class H and Class K by the Defense Logistics Agency.  The SVGA delivers up to 50W of output power, is radiation hardened to 100 krads (Si) including Enhanced Low Dose Rate Sensitivity (ELDRS), and is characterized to SEE of 85 MeV-cm2/mg.

The SVGA Series is the latest addition to VPT's existing line of space DC-DC converters. The SVGA functions as a non-isolated, regulated buck converter that steps down the voltage at the point of use in a distributed power system. From a single, small size, high current package, this module saves significant board space, weight, and cost for power systems headed for LEO, MEO, GEO, and deep space missions.

"To reduce weight and component cost, distributed power systems are relying more on smaller, less expensive point of load converters used in conjunction with the larger, traditional, isolated DC-DC converters. Customer response to our space-qualified, off-the-shelf, point of load DC-DC converters has been phenomenal," explained Monty Pyle, Executive Director of Sales. "We've been asked for a higher current option without the need to waste space and weight stringing together multiple POL converters. We're proud to announce that this product will satisfy the needs of space customers requiring higher power levels and stringent radiation requirements."
