It achieves a response time of less than 1 µs and delivers up to 40.0 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 3.25 to 6.87 Vdc. The VTM V048K060T040’s nominal output voltage is 6 Vdc from a 48 Vdc input Factorized Bus, Vf, and is controllable from 3.25 to 6.87 Vdc at no load, and from 2.95 to 6.60 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 = 1/8 , 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 6 V VTM achieves a power density of 974 W/in3 in a V•I Chip package compatible 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) over the board. A J-lead package option supports on-board surface mounting with a profile of only 0.25" (6 mm) over the board. The VTM’s fast dynamic response and low noise eliminate the need for bulk capacitance at the load, substantially increasing the POL density while improving reliability and decreasing cost.
