AL8116W6-7 from Diodes Incorporated, in a SOT-26. 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 | VCC | power_in | Supply voltage pin; recommended VCC is 10 V to 56 V, and a 0.1 µF to 0.47 µF SMD ceramic capacitor should be placed as close to the IC as possible to filter switching noise. |
| 2 | GND | power_in | Ground or power return pin; all voltages in the datasheet are measured with respect to GND. |
| 3 | OUT | output | Dimming PWM output in open-drain configuration, connected to the power supply through a resistor; recommended sink current is up to 20 mA, with absolute maximum 30 mA and voltage up to 56 V. |
| 4 | ISET | passive | Sets the DIM pin bias current through resistor RISET to GND, with RISET recommended between 33 kΩ and 330 kΩ and an absolute maximum voltage of -0.3 V to +6 V. |
| 5 | CLAMP | passive | Sets the minimum output duty clamp through resistor RCLAMP to GND (0 Ω gives 8%, 150 kΩ gives 6%, 300 kΩ gives 4%, open gives no clamp), with an absolute maximum voltage of -0.3 V to +6 V. |
| 6 | DIM | input | Dimming signal input accepting 0/1 V to 10 V DC, PWM at 0.2 kHz to 10 kHz with high level at or above 3.2 V, or a potentiometer to GND; absolute maximum voltage is -0.3 V to +20 V. |
