description A synchronous rectifier control apparatus includes a continuous conduction mode detection circuit configured to receive a voltage across a synchronous rectifier switch and determine whether the synchronous rectifier switch operates in a continuous conduction mode based on a rising slope of the voltage across the synchronous rectifier switch, a turn-off timer control circuit configured to measure a conduction time of the synchronous rectifier switch and turn off the synchronous rectifier switch after the conduction time of the synchronous rectifier switch in a current cycle is substantially equal to the conduction time measured in an immediately previous cycle, and a drive voltage control circuit configured to reduce a gate drive voltage of the synchronous rectifier switch after the conduction time of the synchronous rectifier switch in the current cycle is substantially equal to the conduction time measured in the immediately previous cycle multiplied by a predetermined percentage.
