Abstract:
A switching power supply circuit with synchronous rectifier has an energy storage component, a rectifier switch coupled to a secondary side of the energy storage component, and a secondary side control circuit. The secondary side control circuit provides a driving signal to control the rectifier switch. When the drain-source voltage across the rectifier switch is less than a first threshold value, the secondary side control circuit controls the driving signal to be a maximum voltage to control the rectifier switch being fully on for a predetermined duration. After a predetermined duration, the secondary side control circuit adjusts the voltage of the driving signal based on the drain-source voltage across the rectifier switch and a second threshold value.

Claim (Index 17):
The switching power supply circuit of  claim 16 , wherein the secondary side control circuit further comprises:\n a first comparison circuit, configured to receive the drain-source voltage across the rectifier switch and the first threshold value, and configured to provide a first comparison signal based on a compare result of the drain-source voltage across the rectifier switch and the first threshold value; a second comparison circuit, configured to receive the drain-source voltage across the rectifier switch and the turn-off threshold value, and configured to provide a second comparison signal based on a compare result of the drain-source voltage across the rectifier switch and the turn-off threshold value; an amplifying circuit, configured to receive the drain-source voltage across the rectifier switch and the turn-on threshold value, and configured to provide an amplified signal based on a difference between the drain-source voltage across the rectifier switch and the turn-on threshold value; and a gate logic circuit, configured to receive the first comparison signal, the second comparison signal and the amplified signal, and configured to generate the driving signal based on the first comparison signal, the second comparison signal and the amplified signal.
