ABSTRACT:
Disclosed are a synchronous rectifier control device and a forward synchronous rectifier circuit. The synchronous rectifier control device is coupled with the secondary side of the forward synchronous rectifier circuit, comprising a condition detecting unit, a reference time circuit and a synchronous signal generator. The condition detecting unit receives at least one reference signal and a detecting signal in response to the condition of the secondary side of the forward synchronous rectifier circuit, and accordingly generates a first synchronous control signal. The reference time circuit is coupled with the condition detecting unit, and generates a reference time signal in response to the first synchronous control signal. The synchronous signal generator generates a second synchronous control signal in response to the first synchronous control signal and the reference time signal.
