Vicor introduces the V048K015T100 V*I Chip Voltage Transformation Module (VTM), designed to meet the demands of advanced DSP, FPGA, ASIC, processor cores and microprocessor applications at the point of load (POL) while providing isolation from input to output. It delivers up to 100 A from a V*I Chip package less than 0.25 cubic inch in volume and responds in a fraction of one microsecond to no load-full load and full load-no load step changes. Optimized for vlow output voltages at high currents, it has efficiency of 90% at 1.2 V/100 A, and better than 92% at 50 A. The VTM may be paralleled to deliver hundreds of amps at an output voltage settable from 0.8 to 1.6 VDC. As a point-of-load current multiplier (32 X) with Mega-Hertz bandwidth, the VTM can eliminate bulk capacitors and the high power distribution losses caused by bussing high currents to the POL.
