Product Description
The V048F480T006 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 6.3 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 26.0 to 55.0 Vdc.
The VTM V048F480T006’s nominal output voltage is
48 Vdc from a 48 Vdc input Factorized Bus, VF, and is
controllable from 26.0 to 55.0 Vdc at no load, and from
24.7 to 53.8 Vdc at full load, over a VF input range of
26.0 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 , 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.
The 48 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.
