Product Description
The V048F240T012 VI 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 s and delivers up to 12.5 A
in a volume of less than 0.290 in3 with unprecedented
efficiency. It may be paralleled to deliver higher power
levels at an output voltage settable from 13.8 to 26.5 Vdc.
The VTM V048F240T012’s nominal output voltage is 24
Vdc from a 48 Vdc input Factorized Bus, Vf, and is
controllable from 13.8 to 26.5 Vdc at no load, and from
13.0 to 25.8 Vdc at full load, over a Vf input range of 28
to 53 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 = 1/2, 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 24 V VTM achieves a power density of 1036 W/in3 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.
