ME2188A45M3G

MICRONE · DC-DC Converters · SOT-23

ME2188A45M3G 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. Common return for input, output and internal control. Must be well-grounded to keep the internal zero reference stable against switching currents.
2 LX power_out Switching node (energy conversion pin). Connects to the external boost inductor (typ. 22 µH) that ties to VIN. Absolute max ±ILX = 1000 mA; voltage rating -0.3 V to 6 V.
3 VOUT power_out Regulated boost output (4.5 V for the A45 option, ±2% accuracy). Also supplies internal circuitry via the synchronous rectifier from LX. Requires an external output capacitor (typ. 100 µF, low-ESR/tantalum recommended).

Provenance

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

  • Datasheet: MICRONE datasheet (12 pp, sha256 b85ddd8e1565166d, 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).
