MX8015EP from Wuxi Maxinmicro, in a ESOP-8. 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 | EN | input | Enable pin. Drive high to enable the converter; drive low to shut it down (shutdown current ~9µA at EN=0V). Start-up threshold is typically 2.2V with 0.2V hysteresis. |
| 2 | VIN | power_in | Chip supply input. Accepts 9V to 100V. Bypass locally with a 47µF bulk capacitor and a low-ESR 1µF ceramic placed close to the pin. UVLO start threshold ~8V with 0.3V hysteresis. |
| 3 | GND | power_in | Chip ground. Connect to the system ground plane along with pin 4 and the exposed thermal pad for thermal dissipation and current return. |
| 4 | GND | power_in | Chip ground. Connect to the system ground plane along with pin 3 and the exposed thermal pad for thermal dissipation and current return. |
| 5 | FB | input | Output voltage feedback pin. Regulates to an internal 0.8V reference; set VOUT with a resistor divider using VOUT = 0.8 × (R1 + R2) / R2. FB short-circuit threshold ~0.35V (0.42V hysteresis). Absolute max: -0.3 to +7V. |
| 6 | NC | unconnected | No connect. Leave floating or tie to ground per PCB layout preference. |
| 7 | BOOT | passive | Bootstrap pin for the high-side NMOS gate driver. Connect a bootstrap capacitor (typ. 0.1µF) between BOOT and SW. Absolute max voltage is VSW-0.3V to VSW+7V. |
| 8 | SW | output | Switching node. Connects to the external inductor and freewheel Schottky diode (D1). Peak current limit 3A; RDS(on) of the internal high-side NMOS is ~400mΩ. Absolute max: -0.3 to +105V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 451 faces against 152 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.
