ME3110AM6G from MICRONE, in a SOT-23-6. 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 | BOOT | passive | Bootstrap capacitor pin for the high-side NMOS gate driver. Connect a ceramic capacitor of at least 0.1 µF between BOOT and LX. Absolute max V(BOOT-LX) = 6 V; V(BOOT-SW) rated -0.3 to 6 V. |
| 2 | GND | power_in | Device ground return. Connect to the ground plane; forms the reference for VIN, EN, FB and internal control circuitry. |
| 3 | FB | input | Feedback voltage input to the inverting input of the internal error amplifier. Regulates to VREF = 0.6 V (±2%, 0.588-0.612 V). Connect the mid-point of the output resistor divider (e.g. R1/R2) here to set VOUT. |
| 4 | EN | input | Enable input. Logic high enables the IC (V_ENH typ 1.3 V, max 1.5 V); logic low disables it (V_ENL min 0.8 V, typ 1.0 V). Absolute max 18 V; do not float. |
| 5 | VIN | power_in | Main supply input for the controller and the high-side power switch. Operating range 4.4 V to 18 V; UVLO rising ~4.3 V typ with 0.25 V hysteresis. Decouple with a low-ESR ceramic capacitor (e.g. 47 µF) close to the pin. |
| 6 | LX | output | Switch node - drain junction of the internal high-side and low-side NMOS power switches. Connect to the output inductor (typ 3.3 µH, 1.2-6 µH) and serves as the reference for the BOOT capacitor. Rated -0.3 V to 18 V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 464 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
