Product Description

Absolute Maximum Ratings

The V048F060T040 VI Chip ? current multiplier 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 40 A in a volume of less than

0.295 in 3 with unprecedented efficiency. It may be

paralleled to deliver higher power levels at an output

voltage settable from 3.25 to 6.87 Vdc.

The VTM V048F060T040’s nominal output voltage is

6 Vdc from a 48 Vdc input Factorized Bus, V F , and is

controllable from 3.25 to 6.87 Vdc at no load, and from

2.97 to 6.61 Vdc at full load, over a V F input range of 26

to 55 Vdc. It can be operated either open- or closed-loop

depending on the output regulation needs of the
