1. AC Input & Rectification – Bridge rectifier, bulk capacitor (100-220 µF, 400V).
2. Transformer – Primary winding connected to Pin 6 (Drain). Auxiliary winding supplies VCC through a diode and resistor.
3. Startup Resistor – High-value resistor (e.g., 1 MΩ) from bulk capacitor to Pin 1 (VCC) for initial startup.
4. Current Sense Resistor – Connected between Pin 7 (Source) and GND, typically 0.22Ω to 0.47Ω / 2W.
5. Feedback Network – Secondary side: TL431 + optocoupler (e.g., PC817) with output connected to Pin 3 (FB).
6. Snubber Circuit – RCD snubber across primary winding to suppress leakage spikes.
7. Secondary Rectification – Schottky diode (e.g., SB5100) and low-ESR capacitor.
