V048K480M006 Datasheet | Vicor Corporation

Description The V048K480T006 V- I Chip Voltage Transformation Module (VTM) excels at speed, density and efficiency to meet the demands of advanced power applications while providing isolation from input to output. It achieves a response time of less than 1 µs and delivers up to 6.3 A in a volume of less than 0.25 in3 with unprecedented efficiency. It may be paralleled to deliver higher power levels at an output voltage settable from 26.0 to 55.0 Vdc. The VTM V048K480T006’s nominal output voltage is 48 Vdc from a 48 Vdc input Factorized Bus, Vf, and is controllable from 26.0 to 55.0 Vdc at no load, and from 24.8 to 53.9 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 , 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 48 V VTM achieves a power density of 1218 W/in3 in a V- I Chip package patible with standard pick-andplace 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 system density while improving reliability and decreasing cost.
