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.

Notes:
Note2: The converter has built in soft start circuit. Rapidly changing the input voltage from VINmin to VIN
can bypass this circuit and damage the converter.

Note3: Operation under no load will not damage the devices, however they may not meet all specifications.
A minimum load of 10mA is recommended.
