AL8807W5-7 from Diodes Incorporated, in a SOT-25. 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 | SW | output | Switch pin for connecting the inductor and freewheeling diode; keep the track short to reduce EMI, with VSW limited to -0.3 V to +40 V relative to GND. |
| 2 | GND | power_in | Ground pin, and the dominant conduction path for heat out of the device, so it should connect to a large ground plane with thermal vias. |
| 3 | CTRL | input | Dimming and on/off control input: below 0.4 V turns off the output current, 0.5 V to 2.5 V sets 20% to 100% of nominal current, PWM high above 2.6 V, and the absolute maximum is -0.3 V to +6 V; leave floating for normal operation. |
| 4 | SET | input | Sets the nominal output current through an external resistor connected between VIN and SET, with a 100 mV nominal set-current threshold (95 mV to 105 mV). |
| 5 | VIN | power_in | Input supply pin for 6.0 V to 36 V operation (absolute maximum -0.3 V to +40 V relative to GND), which must be locally decoupled to GND with more than 2.2 µF X7R ceramic capacitor. |
