Abstract

See full text

A controller for a use with a power converter includes a sensor coupled to sense a signal on a secondary side of the power converter. The sensor is coupled to detect a turn off of a power switch on a primary side of the power converter. A charge source is coupled to charge a control terminal of a synchronous rectifier on the secondary side of the power converter in response to said detection of the turn off of the power switch to a voltage beyond a threshold voltage of the synchronous rectifier to allow the synchronous rectifier to conduct a current of the secondary winding. A linear amplifier having an output is coupled to sink current from the control terminal of the synchronous rectifier in response to a difference between a voltage across the synchronous rectifier and an amplifier reference value.
