I Chip Voltage Transformation

Module (VTM) breaks records for speed, density and

efficiency to meet the demands of advanced DSP,

FPGA, ASIC, processor cores and microprocessor

applications 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 90 A in a

volume of less than 0.25 in

while providing low output

voltages with unprecedented efficiency. It may be

paralleled to deliver hundreds of amps at an output

voltage settable from 0.8 to 1.7 Vdc.

The VTM V048K015T090’s nominal output voltage is

1.5 Vdc from a 48 Vdc input factorized bus, V

, and is

controllable from 0.8 to 1.7 Vdc at no load, and from

0.8 to 1.6 Vdc at full load, over a V

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 V

input voltage with a transformation ratio,

K = 1/32, and an output resistance, R

OUT

= 1.0 milliohm, to

enable applications requiring a programmable low

output voltage at high current and high efficiency.

Closing the loop back to an input Pre-Regulation

Module (PRM) or DC-DC converter can compensate

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.

Part Numbering

The 1.5 V VTM achieves break-through current density

of 360 A/in

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.
