DC-DC PCB MOUNTED CONVERTERS & POWER MODULES V•I Chip PRM Series 244 1 2 0 - 4 0 0 W AT T S - D C / D C P R E - R E G U L AT O R M O D U L E FEATURES • • • • • • • ZVS buck / boost reulator Small footprint: 1.1in2 (7.1cm2). Provides factorised bus for 48 Vin VTMs. J-Lead package. Efficiency: Up to 97%. Pick & place / SMD compatible. High density: Up to 875W/in3. PRE-REGULATOR MODULE (PRM) PRODUCT DESCRIPTION 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.
