VI Chip PRM® ModulePoint-of-load, Buck-Boost regulation Factorized Power
Architecture 500 W in 1.1 in² at 97% Efficiency

Vicor's VI Chip PRM module is a very efficient non-isolated regulator capable of both bucking and boosting a wide range input voltage and provides a regulated, adjustable output voltage. PRMs can be used stand-alone as non-isolated voltage regulators or combined with VTMs for a complete isolated, DC-DC solution with high efficiency and power density.
