Abstract
A synchronous rectification control circuit has a turn-on detection circuit. The turn-on detection circuit has a slope detection circuit and a threshold generation circuit. The slope detection circuit generates a slope representation signal representing a falling slope of the detection signal. The threshold generation circuit generates a threshold signal by selecting one of threshold reference signals according to a driving signal. The turn-on detection circuit generates a comparison result signal by comparing the slope representation signal and the threshold signal for controlling the switch state of the synchronous rectification transistor.
