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.
