R-78HB5.0-0.5-W

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. 0.5 Amp SIP3 Wired 3 Single Output Selection Guide Part Number R-78HB5.0-0.5/W R-78HB12-0.5/W Input Voltage Range (2) [VDC] 9-72 17-72 Output Voltage [VDC] 5.0 12 Output Current [A] 0.5 0.5 Efficiency typ @ min Vin.
