Mosfet synchronous rectifier
WebJul 7, 2024 · 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 for a synchronous rectifier in a Cuk converter – where the mosfet would need to be biased negative of the 0V rail.

WebGreenChip synchronous rectifier controller 8 Functional description 8.1 Introduction The TEA2093TS is a controller IC for synchronous rectification (SR) in asymmetrical half-bridge flyback and standard flyback applications. It can drive the external synchronous rectifier MOSFET for the rectification of the voltage on the secondary winding of the Webswitching MOSFETs in a synchronous rectification circuit. However, an appropriate dead-time based on PCFF has a great influence on the efficiency of the synchronous rectification circuit[7]. If the dead-time is set too long, the amplitude output range will decrease. If the dead-time is set too short, the circuit will be less efficient.
