General Description

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 complexity can be minimized.

Key Features

Low operation current (1.7mA) One resistor for timing setting Internal automatic tracking for optimum dead time No reverse energy flow at light load Best suited for primary green-mode PWM IC Wide supply voltage range from 6V to 20V Built-in 18V Zener diode Optional current sensing: - Current shunt - RC network for better efficiency.
