This series is a new, high efficiency, Quarter-Brick, isolated,
Intermediate Bus Converter series that provides up to 300 Watts of
output power. 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.
