2. VCC: Power supply input for the IC.
3. FB (Feedback): Receives the feedback signal from the output to regulate the power supply's output voltage.
4. COMP (Compensation): Used for compensation and stabilization of the control loop.
5. RT (Timing Resistor): Sets the switching frequency in conjunction with a resistor.
6. CS (Current Sense): Monitors the current through the power switch for overcurrent protection.
7. DRV (Drive): Outputs the PWM signal to drive the gate of an external power MOSFET.
8. NC (No Connection): This pin is typically not connected internally.
These pins work together to provide efficient power conversion and regulation in applications like power adapters and LED drivers.
