Hi Sir,
I wanted to know the the logic behind turn off of high side clamp switch. After analysing the waveforms, I realised that the clamp switch is turned off at the instant when capacitor current reaches negative peak.
In UCC28780, only switch node voltage and switch current are sensed. Leaving the burst mode and other protection features, I wanted to know the basic idea behind turn off instant of this clamp switch and adjusting the dead time between main switch turn off and clamp switch turn on.
Thank you
