Small converter delivers 80 A at 0,9 to 1,8 V

5 November 2003 Power Electronics / Power Management

Vicor has introduced its first V•I chip voltage transformation module (VTM), the V048K015T80. 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, the VTM achieves a response time of less than 1 µs and delivers up to 80 A in a volume of less than 4,1 cm3 while converting 48 V to 1,5 V with high efficiency.

VTMs may be paralleled to deliver hundreds of amperes at an output voltage settable from 1,0 to 1,8 V d.c., at no load, and 0,9 to 1,7 V d.c., at full load. The V•I Chip outline dimensions are 32 x 21,5 x 6 mm.

The V•I Chip VTM is a key component of the Factorized Power Architecture recently introduced by Vicor. Unlike the Intermediate Bus Architecture, which feeds non-isolated POL converters or VRMs at inefficiently low bus voltages, Factorized Power leverages a voltage, designated Vf, controlled to minimise distribution losses while allowing energy to be densely stored for sudden delivery to or retrieval from the load by isolated VTMs.
