LM27313XMFX

Texas Instruments · DC-DC Converters · SOT-23-5

LM27313XMFX from Texas Instruments, 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 SW output Drain of the internal 30-V, 800-mA DMOS FET switch. Connects to the boost inductor and Schottky diode. Absolute maximum voltage 30 V.
2 GND power_in Analog and power ground reference for the device.
3 FB input Feedback input that connects to an external resistive divider to program VOUT. Internal reference VFB = 1.230 V (typ). Feedback pin bias current 60 nA typ.
4 SHDN input Active-low shutdown control input. Drive above ~1.5 V to enable, below 0.5 V to shut down (survival max 14.5 V). Tie to VIN if the shutdown feature is not used.
5 VIN power_in Analog and power supply input. Recommended operating range 2.7 V to 14 V (absolute max 14.5 V).

Same part, different packaging or reel option.

  • LM27313XMFX

CAD (KiCad official)

  • Symbol: LM27313XMFX
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: lm27313xmfx-etched.step / lm27313xmfx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm27313xmfx.step / lm27313xmfx.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm27313xmfx.step 85 KB You want the bare part, or you mark your own boards.
lm27313xmfx-etched.step 1.7 MB You want the part with LM27313XMFX already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 443 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: Texas Instruments datasheet (30 pp, sha256 3412082d0e90a70d, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
