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. Closing the loop back to an input Pre-Regulation Module (PRM) or DC-DC converter enables tight load regulation. The 4 V VTM achieves a current density of 182 A/in3 in a V•I Chip package compatible with standard pick-andplace and surface mount assembly processes. The VTM’s fast dynamic response and low noise eliminate the need for bulk capacitance at the load, substantially increasing system density while improving reliability and decreasing cost.
