Product Description
The V048F096T025 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 25 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 6.40 to 11.0 Vdc.
The VTM V048F096T025’s nominal output voltage is 9.6
Vdc from a 48 Vdc input Factorized Bus, Vf, and is
controllable from 6.40 to 11.0 Vdc at no load, and from
6.10 to 10.7 Vdc at full load, over a Vf input range of 32
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 = 1/5, for applications requiring an isolated output
voltage with high efficiency. Closing the loop back to an
input PRM
TM
regulator or DC-DC converter enables tight
load regulation.
The 9.6 V VTM achieves a power density of 813 W/in
3
in
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.
