Abstract
A synchronous switching converter with an energy storage component and a synchronous rectifier coupled to the energy storage component, having: a secondary control circuit configured to receive a slew rate threshold adjusting signal and a voltage across the synchronous rectifier, and to provide a secondary control signal; wherein the secondary control circuit detects a slew rate of the voltage across the synchronous rectifier, and maintains the synchronous rectifier being off when the slew rate of the voltage across the synchronous rectifier is lower than a slew rate threshold.
