The heart of any SMPS is its PWM (Pulse Width Modulation) controller. Find the IC's part number on the board and search for its datasheet. The datasheet typically includes a reference application circuit, which is often very close to the actual board layout. For the Wannien 101V0, look for chips like the TSM101 or common eight‑pin PWM controllers like the UC3842 family. Since you likely won't find a PDF schematic,

If you cannot find a schematic using "Wannien 101V0", look closely at the small 8-pin or 6-pin integrated circuit (IC) on the bottom (solder side) of the board. This is the PWM controller (common models include the ). Search for the datasheet or standard application diagram of that specific IC. Because SMPS designs strictly follow the manufacturer's datasheet reference designs, the IC datasheet schematic will be 90% identical to your Wannien board.
