Abstract
Flyback converters and corresponding methods are provided. In an implementation, an on-time of a low-side switch of the flyback converter is kept at half a resonance period of a resonance defined by a leakage inductance of a transformer of the flyback converter and a capacitance value of a capacitor coupled to a primary winding of the transformer. Other methods, controllers and flyback converters are also provided.
