PRELIMINARY
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 μs and delivers
up to 50 A in a volume of less than 0.274 in
3
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 converter
enables tight load regulation.
The 4 V VTM achieves a current density of 182 A/in
3
in
a VI 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.
