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 25A and efficiencies
up to 96%. The 12 Volt power is a great power source for a variety of non-isolated,
point-of-load converters or embedded solutions. 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 under-voltage protection as
well as output over-voltage and over-current protection.
