The 45/48-volt-output MBCM270F450M270A00 and its partner 28/33-volt-output MBCM270F338M235A00 bus converters are available in surface mount technology (SMT), through-hole, and thermally-enhanced VI BRICK package versions. For more information contact Vicor online at www.vicorpower.com.
ANDOVER, Mass., 10 March 2011. Vicor Corp. in Andover, Mass., is introducing the MBCM270F450M270A00 military commercial off-the-shelf (COTS) BCM bus power converter for aircraft, surface ships, submarines, land vehicles, and fixed-site military installations. The device is part of the Vicor (NASDAQ: VICR) V.I Chip power component family.The MBCM270F450M270A00 power electronics device operates from a 270-volt DC (230 to 330 volts) MIL-STD-704E/F power rail, and uses the Sine Amplitude Converter (SAC) proprietary topology to deliver isolated power to a nominal 45-volt rail at more than 96 percent efficiency, Vicor officials say. That is more than 800 Watts per cubic inch of power density with around 0.25-inch profile and one-half ounce in weight.Systems use the MBCM-series bus converters with downstream PRM regulators and VTM current multipliers to drive pulsed-power loads in applications such as radar, as well as in applications like radio and satellite communications, computing processors and ASICs, and memory.
