PN8366SSC-R1M from Wuxi Chipown Micro electronics, in a SOP-7. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Supply pin of the controller, with VDD under-voltage and over-voltage protection (UVLO & OVP) per the feature list. |
| 2 | NC | unconnected | No internal connection. |
| 3 | FB | input | Primary-side feedback input used for CC/CV regulation, removing the need for an optocoupler and TL431. |
| 4 | CS | input | Current-sense input where the Rcs resistor sets output current and power, with CS open/short protection (CS O/SP). |
| 5 | SW | passive | Switching node of the integrated 650V avalanche-capable power MOSFET, tied to the transformer primary and shorted with the other SW pin. |
| 6 | SW | passive | Switching node of the integrated 650V avalanche-capable power MOSFET, tied to the transformer primary and shorted with the other SW pin. |
| 8 | GND | power_in | Ground reference of the controller and power MOSFET return. |
