Regulator
Efficiency up to 96%, no need for heatsinks Build-in diode protection circuit Low profile (LxWxH= 11.5 x 8.5 x 17.5mm) Continuous short circuit protection RoHS compliant IEC/EN60950 certified
DC/DC Converter
R-78W-0.5
Description
The R-78W series offers wired 0.5A switching
regulators which are ideally suited to offer a stable voltage supply without the need for a PCB for applications like high power LED lighting, battery powered systems, cooling systems, or fans. Due to the high efficiencies of up to 96% there is no need for a heat sink. The compact modules feature fully protected outputs and draw only 1mA under no load conditions.
