Abstract: A power conversion circuit including an SR MOSFET is provided. A minimum off-time timer for the SR MOSFET is started. A voltage potential at a first terminal of the SR MOSFET is measured. The SR MOSFET is turned on after a rate of change over time of the voltage potential exceeds a first threshold and before the minimum off-time timer expires.

Abstract: A synchronous rectifier controller includes an exception timer, one or more blanking timers, and control logic. The control logic may detect a beginning of a conduction phase using a current sense signal. In response to detecting the beginning of the conduction phase, the control logic commences the exception timer, commences a first blanking interval, and asserts the drive signal. In response to an OFF condition being detected, the first blanking interval being elapsed, and the exception timer being running, the control logic de-asserts the drive signal and commences a second blanking interval. In response to an ON condition being detected, the second blanking interval being elapsed, and the exception timer being running, the control logic commences a third blanking interval and asserts the drive signal. The control logic may assert and de-assert the drive signal multiple times while the exception timer is running.

Abstract: A switched mode power supply, in some embodiments, comprises a synchronous rectification transistor switch including a gate, and it further comprises an output driver coupled to the gate and providing a driving signal to the gate. The driving signal is determined based on a dynamically controllable clamp signal and a prior driving signal.

Abstract: 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.

Abstract: In one embodiment, a synchronous rectifier controller is configured to initiate forming an off-time interval for a first period of time responsively to the controller forming a disable state of a switching signal wherein the control circuit maintains the switching signal in the disable state for at least the off-time interval. The controller is also configured to restart forming the off-time interval responsively to a voltage of a synchronous rectifier becoming a first value prior to expiration of the first period of time.
