ME2188A28M3G

MICRONE · DC-DC Converters · SOT-23

ME2188A28M3G 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. Must be tied solidly to the system ground plane; the internal zero reference tracks GND, so poor grounding causes it to shift with switching current and produces unstable operation.
2 LX power_out Switching node / energy-conversion pin. Connects to the external boost inductor (typ. 22 uH) which ties to VIN. Absolute max voltage -0.3 to 6 V; peak switch current ILXmax = 1000 mA (current limit typically 1000 mA, min 800 mA).
3 VOUT power_out Regulated boost output and internal feedback sense. Fixed 2.8 V for the A28 option (±2% accuracy). Also supplies the internal control circuitry; requires an output capacitor (typ. 100 uF, low-ESR/tantalum recommended, ≥40 uF). Abs max -0.3 to 6 V.

  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: me2188a28m3g-etched.step / me2188a28m3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me2188a28m3g.step / me2188a28m3g.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
me2188a28m3g.step 59 KB You want the bare part, or you mark your own boards.
me2188a28m3g-etched.step 2.5 MB You want the part with ME2188A28M3G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 584 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: MICRONE datasheet (12 pp, sha256 aaef5a1b10071fe3, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
