A method and synchronous rectifier controller uses minimum off and on time blanking to avoid switching the switching transistor at incorrect times responsive to transients in the current sense signal. The minimum off time timer is commenced only when the current sense signal is above a reset threshold, and is reset when the current sense voltage falls below the reset threshold. Resetting the minimum off time timer in this manner avoids false starts of the minimum off time timer due to transients and allows the SRC to properly synchronize with the conduction and blocking phases of rectifier operation.
