SI-8001FDE Datasheet (Sanken) - DC-to-DC Step-Down Converter

SI-8001FDE, DC-to-DC Step-Down Converter

The SI-8001FDE DC voltage regulator is a DC-to-DC buck convertor that attains an oscillation frequency of 300 kHz, and has an integrated miniaturized choke coil, allowing it to serve as a small, high efficiency power supply in a compact TO263 package.

The internal switching regulator function provid
