Hi Tim, in this video 12:21, you introduced PCOSS calculation. I have a question that the enegery stored in OSS when high-side FET is turned on, it must be discharged to somewhere else. If this energy is not used by output or the mosfet itself, it must be taken into account as loss as well. Could we use Poss=Coss*V^2*FSW instead of Poss=0.5*Coss*V^2*FSW to calculate the loss? Thank you very much
Really, really helpful. Thank you for this.
you're the goat honestly, thank you for making this series
