Features

 Built-in overload and saturation protection circuits, effectively preventing overload, switching transformer saturation, and output short circuits.

 Uses a 700V bipolar transistor as the switching transistor; its amplification effect is utilized for startup, reducing power consumption of the startup resistor by more than 10 times.

 Integrated switching transistor reduces cost and improves circuit performance.

 Built-in slope compensation circuit, thermal protection circuit, and slope current drive circuit.

 Built-in thermal protection circuit.

 Low startup and operating current.

 Automatic VCC overvoltage limiting.

 Output power consumption less than 0.15W.

 Minimal external components.

 Package: DIP8
