• Input: 85–265V AC rectified to ~120–375V DC
• SN51DP primary side controller
• Transformer (e.g., EE25 core, primary 80T, secondary 12T, auxiliary 8T)
• Output diode (Schottky, e.g., SB540)
• Feedback via TL431 and optocoupler (e.g., PC817)
• EMI filter and snubber (RCD clamp across primary winding)

• Datasheet check: Look at the layout recommendations. High switching currents require a star ground.
