XL1682 from XINLUDA, in a SOP-8. 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 | NC | unconnected | No connection; this pin is not connected internally. |
| 2 | VS | power_in | Rectified input voltage sensing pin that detects the instantaneous rectified sine waveform of the input voltage; VS, VPK and CS are rated -0.3 to 7 V. |
| 3 | VPK | input | Rectified input voltage peak-value sensing pin that detects the peak value of the rectified sine waveform; VS, VPK and CS are rated -0.3 to 7 V. |
| 4 | CS | input | Primary current sensing pin; voltage at CS is rated -0.3 to 7 V. |
| 5 | FB | input | Captures the feedback voltage from the auxiliary winding, used to control no-load output voltage and set the acceleration stop point at start-up; FB input voltage is rated -40 to 10 V. |
| 6 | GND | power_in | Ground; current return for the gate driver and control circuits of the IC. |
| 7 | OUT | output | Gate driver output; driver output current is rated at 300 mA maximum. |
| 8 | VCC | power_in | Supply voltage for the gate driver and control circuits; recommended operating range is 9 V to 21 V (absolute maximum -0.3 V to +35 V). |
