Abstract:
A synchronous rectifier applied to a power converter includes a control signal generation circuit, a pre-attenuation circuit, and a gate driving circuit. The control signal generation circuit generates a control signal corresponding to a previous period of a secondary side of the power converter according to a detection signal corresponding to the previous period, a first reference voltage, and a second reference voltage when the secondary side is turned on. The control signal corresponding to the previous period corresponds to a discharge time of the previous period. The pre-attenuation circuit pre-attenuates agate control signal corresponding to a current period of the secondary side and generates a pre-attenuation signal corresponding to the current period according to the discharge time. The gate driving circuit drives the gate control signal according to the control signal corresponding to the current period, and stops driving the gate control signal according to the pre-attenuation signal.

Claim (Index 7):
The operation method of  claim 5 , wherein the detection signal is a source voltage of a synchronous switch of the secondary side.
