www.mouser.comdesign of T1, the Flyback can operate either in CCM (Continuous Conduction Mode) or DCM (Discontinuous Conduction Mode). In DCM, all the energy stored in the core is delivered to the secondary during the turn off phase (Flyback period), and the primary current falls back to zero before the Q1 switch turns on again.
Power MOSFET Basics - Understanding Voltage Ratings
www.mouser.comthe leakage inductance is discharged by the snubber, followed by a lower VDSOFF during the flyback operation. If the operating mode is DCM, the voltage would settle at supply voltage VIN, before turning on again. It is not clear whether the 80 % derating rule should be applied w.r.t. peak VDS or VDSOFF. While the intent of an 80 % voltage ...
