Product Description
The V048K120T025 VI Chip
Voltage Transformation Module (VTM) breaks records for speed, density and efficiency to meet the demands of advanced DSP, FPGA, and ASIC at the point of load (POL) while providing isolation from input to output. It achieves a response time of less than 1 µs and delivers up to 25 A in a volume of less than 0.25 in3 with unprecedented efficiency. It may be paralleled to deliver hundreds of amps at an output
voltage settable from 6.5 to 13.7 Vdc. The VTM V048K120T025’s nominal output
voltage is 12 Vdc from a 48 Vdc input Factorized Bus, Vf, and is controllable from 6.5 to 13.7 Vdc at no load, and from 6.5 to 13.4 Vdc at full load, over a Vf input range of 26 to 55 Vdc. It can be operated either open- or closedloop depending on the output regulation needs of the application. Operating open-loop, the output
voltage tracks its Vf input volta...
