AX8115A from Lingyang Micro, in a SOT-89-5. 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 | Drain of the internal power switch, rated -0.3 V to 60 V with a continuous switch current of 1.2 A, so keep the SW trace short to limit switching loss. |
| 2 | GND | power_in | Common power and signal ground for the device. |
| 3 | DIM | input | Switch enable and dimming input for analog dimming (0.5 V to 2.5 V) and PWM dimming, with a 6 V absolute maximum; pulling it below 0.3 V shuts the power switch off into standby. |
| 4 | CSN | input | Current-sense input, where the LED sense resistor is connected between CSN and VIN; the absolute range is VIN-0.3 V to VIN+1 V. |
| 5 | VIN | power_in | Supply input with an operating range of 4.8 V to 50 V and an absolute maximum of -0.3 V to 60 V, which must have a bypass capacitor placed close to the pin. |
