Description

The PRM Module is a family of zero-voltage switching (ZVS) buck-boost regulators with a wide range input voltage and a regulated, adjustable output voltage. PRMs can be used stand-alone as non-isolated voltage regulators or combined with VTM current multipliers for an isolated DC-DC solution with higher efficiency and power density than conventional DC-DC converters. 

Specifications
Input Voltages   48 V (36 – 75 V)
Output Voltage   48 V
Output Power   Up to 600 W
Efficiency  
Up to 97%
Dimensions  

Full Chip :
32.5 x 22 x 6.73 mm

Half Chip :
22 x 16.5 x 6.73 mm
