PRELIMINARY

Product Description

The V048K096T025 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 25.0 A in a volume of less than

paralleled to deliver hundreds of amps at an output

voltage settable from 5.20 to 11.0 Vdc.

The VTM V048K096T025’s nominal output voltage is

9.6 Vdc from a 48 Vdc input Factorized Bus, Vf, and is

controllable from 5.20 to 11.0 Vdc at no load, and from

4.95 to 10.8 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 = 1/5 , 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.

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.
