PRELIMINARY VTM VI Chip – VTM Voltage Transformation Module TM V048F040T050 48 V to 4 V VI Chip Converter 50 A (75 A for 1 ms) High density – 182 A/in3 Small footprint – 45 A/in2 Low weight – 0.5 oz (14 g) Pick & Place / SMD 125°C operation 1 s transient response 3.5 million hours MTBF Typical efficiency 94% No output filtering required Vf = 26 - 55 V VOUT = 2.17 - 4.58 V IOUT = 50 A K = 1/12 ROUT = 3.9 mΩ max Actual size Product Description The V048F040T050 VI 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 s 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 conver……
