tmi3411.lbr rebuild the library on adom-lbr 2.32.0. 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 -> 5 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

TMI3411

TMI · DC-DC Converters · SOT-23-5

TMI3411 from TMI, 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. Drive above the EN rising threshold (typ 1.1V @ VIN=5V, 0.9V @ VIN=3.3V; hysteresis ~0.1V) to enable the converter; drive below the falling threshold to shut down (shutdown current <1µA). Do not leave floating. Absolute max 6.5V.
2 GND power_in Device ground return. Also serves as the source connection for the internal low-side N-channel MOSFET and reference for the internal bias.
3 LX output Power switch node output. Connects to the drains of the internal P-channel high-side and N-channel low-side MOSFETs and to the external inductor. RDS(on) typ 180 mΩ (PMOS) / 70 mΩ (NMOS); rated up to 2A output current. Absolute max -0.3 to 6.5V (transient -3.5 to 7.5V for <5ns).
4 VIN power_in Power supply input, 2.5V to 6.0V operating range. UVLO ~2.3V, OVP ~6.5V. Bypass with a low-ESR ceramic capacitor (22µF typ) placed as close as possible to the pin. Absolute max 6.5V.
5 FB input Output voltage feedback. Connect to the mid-point of the external resistor divider from VOUT to GND; internal reference is 0.600V (typ). VOUT = 0.6 × (1 + R1/R2), adjustable from 0.6V up to near VIN.

Ordering variants

Same part, different packaging or reel option.

  • TMI3411

CAD (KiCad official)

  • Symbol: TMI3411
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tmi3411-etched.step / tmi3411-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmi3411.step / tmi3411.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tmi3411.step 85 KB You want the bare part, or you mark your own boards.
tmi3411-etched.step 1.1 MB You want the part with TMI3411 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 306 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:

  • Datasheet: TMI datasheet (13 pp, sha256 250f10783988bd4b, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
