SM2082EGS

Shenzhen Sunmoon Micro · LED Drivers · ESOP-8

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.

Two STEP files. Same geometry, different body top:

File Size Use it when
sm2082egs.step 193 KB You want the bare part, or you mark your own boards.
sm2082egs-etched.step 2.1 MB You want the part with SM2082EGS already on it.

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.
