DC voltage regulator PRM3735

for automotive applicationsCE

The PRM3735 is a high-efficiency regulator converting a wide-range 31 – 58VDC input into a regulated 48VDC output with output power capability up to 2.5kW. The ZVS buck-boost topology enables high switching frequency operations with high conversion efficiency. High switching frequency allows for reduced-size reactive components, enabling high power density. The SM-ChiP package is compatible with standard pick-and-place and surface-mount assembly processes with planar thermal-interface area and superior thermal conductivity.
