1. A circuit comprising:
a conduction detector configured to monitor conduction of a body diode of a synchronous rectifier switch relative to a predetermined
threshold and to generate a detector output that indicates conduction or non-conduction of the body diode; and
a window analyzer configured to generate a timing signal based on the detector output from the conduction detector, the timing
signal indicating if the synchronous rectifier switch is turned off prematurely or is turned off late relative to an on-time
turn off; and
a controller configured to adjust timing of the synchronous rectifier switch based on whether the timing signal indicates
that the synchronous rectifier switch is turned off prematurely or turned off late relative to the on-time turn off.
