volume of less than 0.25 in3 while providing low output

paralleled to deliver hundreds of amps at an output
voltage settable from 1.1 to 2.3 Vdc.
P R E L I M I N A RYThe VTM V048K020T080’s nominal output voltage is
2 Vdc from a 48 Vdc input factorized bus, Vf, and is
controllable from 1.1 to 2.3 Vdc at no load, and from
1.1 to 2.2 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 = 1/24, and an output resistance, ROUT = 1.3 milliohm, to
enable applications requiring a programmable low
output voltage at high current and high efficiency.

Note: The referenced junction is defined as the semiconductor having the highest temperature.
This temperature is monitored by the temperature monitor (TM) signal and by a shutdown comparator.
Closing the loop back to an input Pre-Regulation
Module (PRM) or DC-DC converter can compensate
for ROUT.
Part Numbering
The 2 V VTM achieves break-through current density of
320 A/in3 in a VI Chip package compatible with
standard pick-and-place and surface mount assembly
processes. The VI 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.
