AP8802SG-13 from Diodes Incorporated, in a SOIC-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 | SET | input | Sets the nominal output current through an external resistor RSET connected between VIN and SET, where the VIN-to-SET threshold is nominally 200 mV and the SET voltage is specified from +0.3 V to -5 V measured with respect to VIN. |
| 2 | GND | power_in | Ground pin, and all voltages are referenced to it; the dedicated GND pins must be connected to 0 V. |
| 3 | NC | unconnected | No connection. |
| 4 | VIN | power_in | Input supply pin with an operating input voltage of 8.0 V to 48.0 V relative to GND, which must be locally bypassed. |
| 5 | SW | output | Switch pin that connects the inductor and freewheeling diode, with an absolute maximum of -0.3 V to +50 V, and the track length at this pin should be minimized to reduce EMI. |
| 6 | SW | output | Switch pin that connects the inductor and freewheeling diode, with an absolute maximum of -0.3 V to +50 V, and the track length at this pin should be minimized to reduce EMI. |
| 7 | GND | power_in | Ground pin shown in the SO-8 top-view pin assignment diagram; it is not listed in the SO-8 column of the pin description table. |
| 8 | CTRL | input | Dual-function dimming pin that must stay above 0.2 V to avoid standby shutdown, accepts a PWM signal (open-drain/collector) or an analog voltage between 0.3 V and 2.5 V, has an absolute maximum of -0.3 V to +6 V, and an input impedance of about 50 kΩ. |
