Product Description
The V048K480T006 V鈥 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 碌s and delivers
up to 6.3 A in a volume of less than 0.25 in
3
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 V048K480T006鈥檚 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
24.8 to 53.9 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
, 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 48 V VTM achieves a power density of 1218 W/in
3
in
a V鈥 Chip package compatible with standard pick-and-
place and surface mount assembly processes. The
V鈥 Chip BGA package supports in-board mounting with
a low profile of 0.16" (4 mm) over the board. A J-lead
package option supports on-board surface mounting
with a profile of only 0.25" (6 mm) over the board. The
VTM鈥檚 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.
