Vicor Corp. (Andover, MA) introduced its V048K015T100 V-I Chip™ Voltage Transformation Module™ (VTM). The VTM breaks records for speed, density and efficiency 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 in³ in volume and responds in a fraction of 1µsec to no load/full load and full load/no load step changes. Optimized for low output voltages at high currents, it boasts 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 Vdc to 1.6 Vdc.
The VTM V048K015T100 is rated for a maximum continuous output of 100 A up to 1.5 Vout and 150 W up to 1.6 V over a Vf input range of 26 Vdc to 55 Vdc. It can be operated either open- or closed-loop depending on the output regulation needs of the application. The 1.5 V VTM achieves current density of 400 A/in³ in a V-I Chip package compatible with standard pick-and-place and surface-mount assembly processes. The V-I Chip BGA package supports in-board mounting with a low profile of 0.16 in (4 mm) over the board.
The VTM V048K015T100 in the V-I Chip BGA package is priced at less than $0.20 per amp in OEM quantities, and is available in JEDEC trays or taped and reeled for automated pick-and-place and SMD assembly. Prototype quantities are available now.
