Many of today’s switching power supplies implement synchronous rectifiers to improve efficiency. In isolated topologies, the power-supply controller typically is located on the primary side of the ...

ON Semiconductor has introduced a self-contained synchronous rectifier that helps designers achieve higher power density in switching power supply designs that previously required discrete solutions.

The most basic diagrams depicting non-isolated DC-DC converters generally show two ideal switches and an energy storage inductor. In early designs, it was quickly realized that one switch could be ...

When comparing diode and synchronous rectifiers, note that the synchronous rectifier MOSFET doesn't always replace the usual Schottky diode. To prevent switching overlap of the high-side and low-side ...
