Abstract
A control circuit for controlling a synchronous rectification switch of a resonant converter, where in a switching cycle, the control circuit is configured to: delay a first time period from a first moment; control the synchronous rectification switch to be turned on when a drain-source voltage of the synchronous rectification switch reaches a first threshold after the first time period; and where the first time period is generated based on an operating state of the synchronous rectification switch in a previous switching cycle.
