P R E L I M I N A RYThe VTM V048K015T80’s nominal output voltage is
1.5 Vdc from a 48 Vdc input factorized bus, Vf, and is
controllable from 1.0 to 1.8 Vdc at no load, and from
0.9 V to 1.7 V at full load, over a Vf input range of 32 to
57.6 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=1/32, and an output resistance, ROUT =1.3 milliohm,
to enable applications requiring a programmable low
output voltage at high current and high efficiency.

The 1.5V VTM achieves break-through current density
of 320 A/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" (4mm) over the
board. A J-lead package option supports on-board
surface mounting with a profile of only 0.25" (6mm)
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.

Application Note
Parallel Operation
In applications requiring higher current or redundancy, VTMs
can be operated in parallel without adding control circuitry or
signal lines. To maximize current sharing accuracy, it is
imperative that the source and load impedance on each VTM in
a parallel array be equal.
To achieve matched impedances, dedicated power planes
within the PC board should be used for the output and output
return paths to the array of paralleled VTMs. This technique is
preferable to using traces of varying size and length.
The VTM power train and control architecture allow bi-directional
power transfer when the VTM is operating within its specified
ranges. Bi-directional power processing improves transient
response in the event of an output load dump. The VTM may
operate in reverse, returning output power back to the input
source. It does so efficiently.
