The series is designed to convert 48 Volts ±10% to a loosely regulated 12 Volts at full rated load up to 25 A and efficiencies up to 96%. This converter is available in four package types, standard quarter-brick through-hole, through-hole vertical, standard quarter-brick surface-mount, and quarter-brick surface-mount solder ball. In addition, this series features remote ON/OFF, no-load operation, input undervoltage protection as well as output overvoltage and overcurrent protection.
