Abstract
A method and circuit controls a synchronous rectifier. The synchronous rectifier is turned OFF by driving a gate of the synchronous rectifier to one or more first voltages that are non-zero. One or more values of the drain or the source of the synchronous rectifier are monitored. The gate of the synchronous rectifier is driven to a second voltage that is less than the one or more first voltages whenever the one or more values of the drain or the source of the synchronous rectifier pass above or below one or more threshold values.
