Abstract
A switching-type regulation driver includes a transformer, a controller, a synchronous rectifier and a drive control module. The drive control module is connected to the synchronous rectifier and the non-dotted terminal of the secondary winding respectively, and is used to detect a target parameter of a voltage across both power ends of the synchronous rectifier when the synchronous rectifier disconnects the conductive path between the non-dotted terminal of the secondary winding and the reference ground. When it is detected that the target parameter of the voltage across both power ends of the synchronous rectifier meets a preset condition, the controller controls a switching action of the first transistor so that the primary winding transmits power to the secondary winding. According to the present disclosure, the pre-stage chip may be matched with to realize a function of dynamic acceleration, and the dependence on the output pin may be reduced.
