Overview
Features Switching Regulator • Efficiency up to 93%, no need for heatsinks • High voltage input range, up to 72VDC • Short circuit protection, thermal shutdown • All-in-one solution, no external components required • IEC/EN60950-1 + AM:2 certified DC/DC Converter R-78HB/W Description The R-78HBxx/W series high efficiency, high input voltage switching regulators are ideally suited to replace 78xx linear regulators.
The efficiency of up to 93% means that very little energy is wasted as heat so there is no need for any heat sinks with their additional space and mounting costs.
A wide input voltage range allows the full stored energy utilization of standard 12, 24 and 36V batteries as well as COB LED drivers.
No external components are required to make a complete regulated, short-circuit protected supply.
A built-in protection diode allows high capacitive loads.
Typical applications include Auxiliary fan CV power supplies powered from CC LED drivers, industrial, aerospace and battery powered applications.
