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 ...

Power supplies that use diodes to rectify an ac voltage to obtain a dc voltage must deal with inherent inefficiencies. A standard diode or ultra-fast diode can have a 1-V forward voltage or higher at ...

After discussing the three transistor high-side buck p-mosfet driver (a recognised circuit and not mine) with some of EW’s sage commenters, I wondered once again if I could design something similar ...

Maximizing energy efficiency and power density have now become requirements for power supply designs in low power chargers and adapters. It has become necessary for synchronous rectification (SR) to ...
