AL8861MP-13 from Diodes Incorporated, in a MSOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ISENSE | input | Current sensing input; connect external resistor RS between VIN and this pin to define nominal average output LED current (IOUTNOM = 0.1/RS). |
| 2 | GND | power_in | Ground (0V) reference. |
| 3 | GND | power_in | Ground (0V) reference. |
| 4 | VSET | input | Multi-function control input for on/off control (disable <0.2V), analog dimming via DC voltage (0.3-2.5V for 5-100% output current range), PWM dimming (recommended <500Hz), and soft-start capacitor connection to GND (additional delay ~1.5ms/nF). |
| 5 | LX | output | Drain of internal 40V NDMOS power switch; high-side switching node in buck converter topology that connects to inductor and freewheeling diode. |
| 6 | LX | output | Drain of internal 40V NDMOS power switch; high-side switching node in buck converter topology that connects to inductor and freewheeling diode. |
| 7 | N/C | unconnected | No internal connection. |
| 8 | VIN | power_in | Input power supply voltage (4.5-40V); must be decoupled to ground with 10μF or higher X7R ceramic capacitor placed close to device. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
