<p>In a controller (CC2) for controlling a synchronous rectification switch (S2), the controller (CC2) comprises a sensing circuit (SRL) for sensing an output (D2) of the synchronous rectification switch (S2) at an end of a blanking time to obtain a sense signal (Q), and a control signal generating circuit (AND1) for generating a control signal (G2) for the synchronous rectification switch (S2) in dependence on the sense signal (Q).</p> |
