SG6203 Overview
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 required and the circuit plexity can be minimized.
SG6203 Key Features
- Low operation current (1.7mA) One resistor for timing setting Internal automatic tracking for optimum dead time No rever
- Current shunt
- RC network for better efficiency
