Product Description
The V048K120T025 V•I Chip Voltage Transformation
Module (VTM) breaks records for speed, density and
efficiency to meet the demands of advanced DSP, FPGA,
and ASIC at the point of load (POL) 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 0.25 in3 with unprecedented
efficiency. It may be paralleled to deliver hundreds of
amps at an output voltage settable from 6.5 to 13.7 Vdc.
The VTM V048K120T025’s nominal output voltage is
12 Vdc from a 48 Vdc input Factorized Bus, Vf, and is
controllable from 6.5 to 13.7 Vdc at no load, and from
6.5 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 a programmable
output voltage at high current and high efficiency.
Closing the loop back to an input Pre-Regulation Module
(PRM) or DC-DC converter enables tight load regulation.
The 12 V VTM achieves break-through power density of
1200 W/in3 in a V•I Chip package compatible with
standard pick-and-place and surface mount assembly
processes. The V•I 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’s fast dynamic response and low noise
eliminate the need for bulk capacitance at the load,
substantially increasing the POL density while improving
reliability and decreasing cost.
