The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 3 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

ME2188A50M3G

MICRONE · DC-DC Converters · SOT-23

ME2188A50M3G from MICRONE, in a SOT-23. 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 Device ground reference. Must be tied solidly to system ground; per the datasheet's PCB layout note, incomplete grounding lets the internal zero-potential shift with switching current and destabilizes operation.
2 LX power_out Switching node (energy-conversion pin). Connects to the external boost inductor (typ. 22 µH) whose other terminal ties to VIN. Absolute max on LX is -0.3 to 6 V; ILXmax rated 1000 mA (current limit typ. 1000 mA, min 800 mA).
3 VOUT power_out Regulated boost output, fixed 5.0 V (±2%) for the A50 option code. Requires an external output capacitor (recommended 47 µF or larger, low-ESR tantalum preferred; 100 µF used in the typical application). Absolute max -0.3 to 6 V; rated 300 mA.

  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: me2188a50m3g-etched.step / me2188a50m3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me2188a50m3g.step / me2188a50m3g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me2188a50m3g.step 59 KB You want the bare part, or you mark your own boards.
me2188a50m3g-etched.step 2.4 MB You want the part with ME2188A50M3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 572 faces against 69 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.
