Pin Count and Functions:
1. DRAIN (Pin 1 and Pin 2): These pins connect to the switching MOSFET's drain and the input voltage. They are used for high-voltage power switching and also provide power to the IC.

2. BYPASS/MULTI-FUNCTION (Pin 3): This pin serves several functions, including setting the current limit, adjusting the line under-voltage threshold, and providing operating power to the IC through an external bypass capacitor.
3. FEEDBACK (Pin 4): This pin is used to regulate output voltage. It senses the output voltage indirectly via the transformer and adjusts the duty cycle accordingly.
4. SOURCE (Pin 5, Pin 6, and Pin 7): These are the source pins for the internal MOSFET and are connected to the primary-side ground. They also serve as the reference point for the IC's control circuitry.
8. NC (Pin 8): This pin is usually not connected internally and is often left floating or used for mechanical stability.
