The PRM is a very efficient non-isolated regulator capable of both boosting and bucking a wide range input voltage and provides a regulated, adjustable output voltage or "Factorized Bus". PRMs can be used stand-alone as non-isolated voltage regulators or combined with VTMs for a complete isolated, DC-DC solution with higher efficiency and power density. The VTM provides point-of-load, fixed ratio voltage transformation with extremely fast transient response and isolation to 2,250 Vdc. Input Voltage
