Discrete sync rectifier for flyback
Webδ Off-line flyback regulators are mainly used for an output power ranging from 30W up to 250W. Flyback topology is dedicated to multiple low cost output SMPS as there is no filter inductor on the output. Figure 5 : Isolated single switch flyback * Secondary Rectifier: V inmax n V RRM ≥V out + V CEV or V DSS ≥ V inmax + nV out WebMar 21, 2024 · The main problem for synchronous rectification is the ringing. If you have a topology such as flyback, the stress and ringing on the output Mosfets and diodes are …
