ICW3115AM6G from ICW, in a SOT23-6. 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 | BOOT | power_out | A ceramic capacitor of at least 0.1 uF must be connected between BOOT and LX to supply the high-side switch driver. |
| 2 | GND | power_in | Ground pin. |
| 3 | FB | input | Feedback voltage pin connected to the inverting input of the error amplifier, with a 0.6 V reference (±2%). |
| 4 | EN | input | Enable input pin; the chip operates when the input logic is high, and VEN is rated -0.3 V to 18 V. |
| 5 | VIN | power_in | Power input for the controller and the converter switches, operating from 4.4 V to 18 V. |
| 6 | LX | output | Switch node connected to the inductor, rated -0.3 V to 18 V. |
