Instructions for Use:

1. Power Supply Connection: Connect the power supply voltage to pin 7 (Vcc). Ensure the voltage is within the operating range of 8V to 40V.
2. Grounding: Connect pin 4 to ground (GND).
3. Frequency Setting: Set the oscillator frequency by connecting an external resistor and capacitor between pins 6 (RT/CT) and ground.
4. Error Amplifier Compensation: Connect compensation components to pins 1 (IN+) and 2 (IN-) for proper feedback loop stability.
5. Output Stage: Connect the output transistor or MOSFET driver to pin 5 (OUT).
6. Bias Supply: Provide a bias supply to pin 8 if using an external bias supply; otherwise, it can be left floating.
7. Thermal Considerations: Ensure adequate heat dissipation if operating at high currents or temperatures.
8. Overcurrent Protection: The IC has built-in overcurrent protection which limits the output current to prevent damage.

For detailed design considerations and application circuits, refer to the datasheet provided by the manufacturer.
