SG6203 Datasheet (Fairchild Semiconductor) - Synchronous Rectifier Controller

SG6203, Synchronous Rectifier Controller

The SG6203 is designed to control and drive the synchronous rectifier for the flyback converter.

The synchronous signal of the primary switch is obtained by a single diode connected between the transformer secondary winding and the SG6203.

Using the SG6203, no additional transformer winding is requi
