Programmable Synchronous Rectifier for Zero Voltage Switching

The synchronous output rectifier of a power converter may be used to facilitate Zero Voltage Switching (ZVS) of the main power switch of the power converter to reduce switching losses. The duration of time which the synchronous output
rectifier is turned ON to facilitate ZVS, e.g. TZVS_ON, along with the delay time between turning OFF the synchronous output rectifier and turning ON the power switch, e.g. TZVS_DLY, may be programmable.
