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. Much googling (and …
