Notes  
The V048F080T030 V•I Chip Voltage Transformation  
Module excels at speed, density and efficiency to meet  
the demands of advanced power applications while  
providing isolation from input to output. It achieves a  
response time of less than 1 µs and delivers up to 30 A in  
a volume of less than 0.295 in3 with unprecedented  
efficiency. It may be paralleled to deliver higher power  
levels at an output voltage settable from 4.34 to 9.16 Vdc.

The VTM V048F080T030s nominal output voltage is 8  
Vdc from a 48 Vdc input Factorized Bus, Vf, and is  
controllable from 4.34 to 9.16 Vdc at no load, and from  
4.04 to 8.89 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 = 1/6, for applications requiring an isolated output  
voltage with high efficiency. Closing the loop back to an  
input PRMTM regulator 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 8 V VTM achieves a power density of 813 W/in3 in  
a V•I Chip package compatible with standard pick-and-  
place and surface mount assembly processes. The VTMs  
fast dynamic response and low noise eliminate the  
need for bulk capacitance at the load, substantially  
increasing system density while improving reliability  
and decreasing cost.
