Notes  
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 in3 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, Vf, 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 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 = 1/32, and an output resistance, ROUT = 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  
for ROUT.

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.
