Notes  
The V048K030T070 V•I Chip Voltage Transformation  
Module (VTM) breaks records for 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 70 A in a  
volume of less than 0.25 in3 with unprecedented  
efficiency. It may be paralleled to deliver hundreds of  
amps at an output voltage settable from 1.63 to 3.43  
Vdc.

The VTM V048K030T070s nominal output voltage is  
3 Vdc from a 48 Vdc input Factorized Bus, Vf, and is  
controllable from 1.63 to 3.43 Vdc at no load, and from  
1.49 to 3.29 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 = 1/16, 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.

Note:  
(1) The referenced junction is defined as the semiconductor having the highest temperature.  
This temperature is monitored by a shutdown comparator.  
The 3 V VTM achieves break-through current density of  
284 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" (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 VTMs 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.
