Considerations for choosing the right flyback diode and rating

WebUsing a flyback converter for low- and medium-power applications is the preferred design choice due to the flyback converter’s simplicity and low cost. However, in isolated applications, the use of optocoupler or auxiliary winding for voltage feedback across the isolation boundary increases the number of components, and design complexity. WebSingle switch versus double switch flyback In the single switch flyback, an overvoltage spike is applied across the power switch at each turn off. The peak value of this overvoltage depends upon the switching time, the circuit capacitance and the primary to secondary transformer leakage inductance.
