Product Description

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 80 A in a

voltages with unprecedented efficiency. It may be

paralleled to deliver hundreds of amps at an output

voltage settable from 1.1 to 2.3 Vdc.

The VTM V048K020T080’s nominal output voltage is

controllable from 1.1 to 2.3 Vdc at no load, and from

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

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

The 2 V VTM achieves break-through current density of

standard pick-and-place and surface mount assembly

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.
