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 voltage with a transformation ratio, K = 1/4 , for applications requiring a programmable output voltage at high current and high efficiency. Closing the loop back to an input Pre-Regulation Module (PRM) or DC-DC converter enables tight load regulation. The 12 V VTM achieves break-through power density of 1200 W/in3 in a V- I Chip package patible 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" (4 mm)...
