Notes
The V048F120T025 V•I 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 25 A in a volume of less than
0.295 in3 with unprecedented efficiency. It may be
paralleled to deliver higher power levels at an output
voltage settable from 6.50 to 13.8 Vdc.

The VTM V048F120T025’s nominal output voltage is 12
Vdc from a 48 Vdc input Factorized Bus, Vf, and is
controllable from 6.50 to 13.8 Vdc at no load, and from
6.16 to 13.4 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 = 1/4 , for applications requiring an isolated output
voltage with high efficiency. Closing the loop back to an
input PRMTM regulator or DC-DC converter enables tight
load regulation.

Notes:
[a] 245°C reflow capability applies to product with manufacturing date code 1001 and greater.
[b] The referenced junction is defined as the semiconductor having the highest temperature.
This temperature is monitored by a shutdown comparator.
The 12 V VTM module achieves a power density
of 1017 W/in3 in a V•I Chip package compatible with
standard pick-and-place and surface mount assembly
processes. The VTM modules 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.
