Abstract
A synchronous rectification controller controls a synchronous rectifier with a control node and a detection node. The synchronous rectification controller comprises an ON-time recorder and a differential driver. The ON-time recorder records a previous ON-time in response to a detected voltage at the detection node, and determines first and second regulation periods in an ON time of the synchronous rectifier based on the previous ON-time. The first regulation period occurs prior to the second regulation period. The differential driver drives the control node to regulate the detected voltage to first and second target voltages during the first and second regulation periods, respectively. The first and second target voltages are different from each other.
