SM2082EGS from Shenzhen Sunmoon Micro, 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 | GND | power_in | Chip ground reference. |
| 2 | REXT | input | Output-current setting pin. Connect an external resistor Rext from this pin to GND to program the constant output current per IOUT = VREXT / Rext = 0.6V / Rext. Typical VREXT = 0.6V (0.58-0.62V) at VOUT=10V. Absolute max on this pin: -0.5V to 8V. |
| 3 | NC | unconnected | No connect. Leave floating. |
| 4 | NC | unconnected | No connect. Leave floating. |
| 5 | NC | unconnected | No connect. Leave floating. |
| 6 | NC | unconnected | No connect. Leave floating. |
| 7 | OUT | power_in | Power input and constant-current output pin. Connects to the LED string return; the internal power MOSFET regulates current to the value set by REXT. Withstand voltage 450V (absolute max -0.5V to 450V); constant-current knee VOUT_MIN ≤ 6.5V at IOUT=30mA. |
| 8 | NC | unconnected | No connect. Leave floating. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 498 faces against 63 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.
