Product Description
The V048K060T040 V•I Chip Voltage Transformation
Module (VTM) excels at 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 40.0 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 3.25 to 6.87 Vdc.
The VTM V048K060T040’s nominal output voltage is
6 Vdc from a 48 Vdc input Factorized Bus, Vf, and is
controllable from 3.25 to 6.87 Vdc at no load, and from
2.95 to 6.60 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 = 1/8 , 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 6 V VTM achieves a power density of 974 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.
