PN8307HSEC-R1 from Wuxi Chipown Micro electronics, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground / source of the internal power MOSFET. Tie to secondary-side return. |
| 2 | GND | power_in | Ground / source of the internal power MOSFET. Connected in parallel with pin 1. |
| 3 | NC | unconnected | No connection. Leave floating. |
| 4 | VCC | power_in | Supply input, 3.6V-20V operating range (absolute max 26V). Startup threshold VCCon ≈ 3.8V, UVLO VCCoff ≈ 3.3V. Bypass with C1 placed close to VCC/GND; typically fed from Vout through series resistor R1. |
| 5 | SW | power_out | Drain of the internal 60V/12mΩ synchronous-rectifier power MOSFET. Connects to the secondary-winding side of the transformer. Rated for 40A max pulse drain current; VDS abs-max 60V. |
| 6 | SW | power_out | Drain of the internal power MOSFET (paralleled with pins 5/7/8 for current-carrying capacity). |
| 7 | SW | power_out | Drain of the internal power MOSFET (paralleled with pins 5/6/8 for current-carrying capacity). |
| 8 | SW | power_out | Drain of the internal power MOSFET (paralleled with pins 5/6/7 for current-carrying capacity). |
