ME3102AM5G

MICRONE · DC-DC Converters · SOT-23-5

ME3102AM5G from MICRONE, in a SOT-23-5. 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 EN input Chip enable input. Drive above V_EH (>=1.5V) to enable the converter; drive below V_EL (<=0.3V) for shutdown (I_SD ~0.1µA). Do not leave floating.
2 GND power_in Device ground. Return for input decoupling and internal synchronous rectifier; connect to system ground plane with a low-impedance path.
3 SW output Switching node. Connects to the drain of the internal PMOS main switch and NMOS synchronous rectifier. Connect the external inductor (0.6µH-4.7µH) here. Absolute max -0.3V to V_IN.
4 VIN power_in Power supply input, 2.5V to 5.5V (absolute max 6.0V). Bypass with a 22µF plus 0.1µF ceramic capacitor to GND as close to the pin as possible.
5 FB input Feedback input to the internal error amplifier. Regulated to V_FB = 0.6V (typ). Connect to the resistor divider from the output (Vo = 0.6 × (1 + R1/R2)). Absolute max 6.0V.

CAD (KiCad official)

  • Symbol: ME3102AM5G
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: me3102am5g-etched.step / me3102am5g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); me3102am5g.step / me3102am5g.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
me3102am5g.step 85 KB You want the bare part, or you mark your own boards.
me3102am5g-etched.step 1.9 MB You want the part with ME3102AM5G already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 464 faces against 102 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:
