It achieves a response time of less than 1 µs and delivers up to 50 A in a volume of less than 0.274 in3 with unprecedented efficiency. It may be paralleled to deliver higher power levels at an output voltage settable from 2.17 to 4.58 Vdc. The VTM V048F040T050’s nominal output voltage is 4 Vdc from a 48 Vdc input Factorized Bus, Vf, and is controllable from 2.17 to 4.58 Vdc at no load, and from 1.98 to 4.40 Vdc at full load, over a Vf input range of 26 to 55 Vdc. It can be operated either open- or closed-loop 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 = 1/12, for applications requiring an isolated output voltage with high efficiency.
