Quarter-Brick Series Narrow Input IBC DC/DC CONVERTERS * * * * * * * * * * 240 to 300W Intermediate Bus Converters 1 NEW Product 48V input with isolated 12V output Efficiencies up to 96% Open loop regulation Fully rated 240W @ 70C, 200 LFM Over-current protection Operates with no load Auto restart after fault condition Remote ON/OFF Parallelable Over-temperature protection 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.
