Assuming identical voltage and current rating, which is having higher switching speed? MOSFET or Schottky diode?
In synchronous buck converter, we replace Schottky diode with MOSFET (low side) for reducing the conduction loss. I want to understand the impact on switching loss due to this.
I realise MOSFET gate-source terminals act like a capacitor which needs to be charged and discharged everytime switching occurs. Whereas Schottky diode is a majority carrier device which requires no recombination of minority carriers. So can I say Schottky diode would be faster? I'm not sure whether I'm comparing apples to oranges.
