tmi3113.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 -> 6 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

TMI3113

TMI · DC-DC Converters · SOT-23-6

TMI3113 from TMI, in a SOT-23-6. 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 pin. Drive above EN rising threshold (typ 1.1V @VIN=5V, 0.9V @VIN=3.3V) to turn the part on; drive below EN falling threshold (typ 1.0V @VIN=5V, 0.9V @VIN=3.3V) to turn it off. Do not leave floating. EN leakage <=1uA. Absolute max 7V.
2 GND power_in Device ground return pin. All internal references and MOSFET source (low-side) currents return through this pin.
3 LX output Power switch (inductor) node. Connects to the drains of the internal P-channel high-side and N-channel low-side MOSFETs. Connect the external inductor here. Absolute max -0.3V to 7V (transient -3.5V to 8.5V for <5ns). PMOS RDS(on) ~95mOhm, NMOS RDS(on) ~50mOhm, peak current limit ~3.5A (typ).
4 VIN power_in Analog and power supply input pin. Operating range 2.7V to 5.5V; input OVP threshold typ 6.1V; input UVLO typ 2.5V rising with ~500mV hysteresis; absolute max 7V. Bypass with a low-ESR ceramic capacitor (22uF X5R/X7R typical) close to the pin.
5 PG output Power-Good open-drain output (TMI3113 only). Goes high-impedance when the output voltage rises above ~91% of the regulated nominal voltage and is pulled low when the output falls below the threshold or when EN is pulled low. Sink capability 2mA max. Requires an external pull-up resistor.
6 FB input Output voltage feedback pin. Internal reference is 0.600V (typ); an external resistor divider from VOUT programs the output per VOUT = 0.6 x (1 + R1/R2). In PFM/no-load operation FB regulates slightly above 0.6V (typ 0.609V). Absolute max 7V.

CAD (KiCad official)

  • Symbol: TMI3113
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: tmi3113-etched.step / tmi3113-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmi3113.step / tmi3113.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tmi3113.step 97 KB You want the bare part, or you mark your own boards.
tmi3113-etched.step 1.3 MB You want the part with TMI3113 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 345 faces against 117 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.
