Product Description

The V048F030T070 V•I Chip Voltage Transformation

Module 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 70 A in

efficiency. It may be paralleled to deliver higher power

levels at an output voltage settable from 1.63 to 3.43 Vdc.

The VTM V048F030T070’s nominal output voltage is 3

Vdc from a 48 Vdc input Factorized Bus, Vf, and is

controllable from 1.63 to 3.43 Vdc at no load, and from

1.49 to 3.31 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 = 1/16, for applications requiring an isolated output

voltage with high efficiency. Closing the loop back to an

input PRM

load regulation.

a V•I Chip package compatible with standard pick-and-

place 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.
