Switching regulators extend efficiency in battery-powered applications

The 9.0 to 48V input range of the Recom R-78HB switching regulators allow appliances to run for longer from a standard 12, 24 or 36V battery by using all of the battery’s stored energy.

As well as the wide input range, the regulators maintain high efficiency of up to 93%, with quiescent current of only 5mA (maximum) and can run heatsink-free to save cost, size and complexity. With short-circuit protection, input filter and a protective diode for powering highly capacitive loads built in, the modules are self-contained and require no additional external components.

Two versions are available, offering 5.0 and 12V single output. The R-78HB5.0-0.5/W and R-78HB12-0.5/W are suitable for supplying up to 0.5A to industrial or aerospace applications or to provide an auxiliary constant voltage from a constant-current LED driver.

The regulators are certified according to IEC/EN-60950-1 general safety and EN55022 Class B EMC standards as well as EN61000-4-2 ESD-standard.

The modules are packaged as 12.1 x 9.7 x 24.0mm SIP3 wired devices that enable the direct replacement of traditional 78xx linear regulators.
