Vicor Introduces 28V MIL-COTS DC-To-DC Chip Modules

The company's MIL-COTS, 28V dc/dc VI chip modules consist of a 28 Vdc input PRM regulator and a family of VTM current multipliers with output voltages from 1 to 50 Vdc. The PRM and VTM chipset provides all the functionality of a dc/dc converter. Each module weighs 0.5 oz. and measures 1.28" x 0.87" x 0.26", making them desirable for portable and airborne applications. A PRM and VTM chipset provides up to 100A or 115W and, because the PRM can be located or factorized remotely from the point of load, these current and power densities can effectively be doubled at the load itself. The modules may be paralleled for higher power arrays. A compatible EMI filter, the M-FIAM7, is available that provides filtering in compliance with MIL-STD-461 and transient suppression in compliance with MIL-STD-1275, MIL-STD-704, and DO-160. A MIL-COTS PRM and VTM chipset is available for less than $170 each in OEM quantities. VICOR CORP., Andover, MA. (800) 735-6200.
