Product Description
The V048K030T070 V鈥 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 碌s and delivers up to 70 A in a
volume of less than 0.25 in
3
with unprecedented
efficiency. It may be paralleled to deliver hundreds of
amps at an output voltage settable from 1.63 to 3.43
Vdc.
The VTM V048K030T070鈥檚 nominal output voltage is
3 Vdc from a 48 Vdc input Factorized Bus, Vf, and is
controllable from 1.63 to 3.43 Vdc at no load, and from
1.49 to 3.29 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 = 1/16, 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 3 V VTM achieves break-through current density of
284 A/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 the POL density while improving
reliability and decreasing cost.
