AL5816QW5-7 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 | PWM | input | PWM signal for high-frequency dimming of the LED, with a high-level input of 2.7V to 60V and a low-level input of 0V to 2.3V. |
| 2 | GND | power_in | Ground reference for the device; the supply and pin voltages are specified relative to GND. |
| 3 | FB | input | Feedback input that regulates to 200mV nominally (VFB 0.19V to 0.21V), with a sense resistor between FB and GND setting the LED current. |
| 4 | OUT | output | Driving output to external transistors, with a recommended OUT voltage range of 0V to 3V and an OUT pin current of 0mA to 15mA. |
| 5 | VCC | power_in | Input supply power with a recommended supply voltage range of 4.5V to 60V relative to GND. |

Package_TO_SOT_SMD:SOT-23-5 - 3D model: SOT-25, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.1 mm tall, datasheet A, nominal). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
