LMR14206XMKX

Texas Instruments · DC-DC Converters · SOT-23-6

LMR14206XMKX from Texas Instruments, 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 CB passive Bootstrap capacitor pin providing the high-side switch FET gate bias voltage. Connect a bootstrap capacitor (CBOOT) between CB and SW. Absolute max: CB-to-SW voltage 7 V.
2 GND power_in Device ground connection. Provides return path for both control circuitry and power stage.
3 FB input Feedback input pin. Set output voltage divider ratio so that VOUT = VFB(1+R1/R2) with VFB = 0.765 V nominal (0.747-0.782 V). Divider resistors should be in the 100 Ω to 10 kΩ range to avoid input bias errors (IFB ≈ 0.1 µA typical). Absolute max: -0.3 V to +5 V.
4 SHDN input Active-low logic-level shutdown input (overbar in datasheet). Pull to GND to disable, pull high to enable (VSHDN on threshold ≥2.3 V, off threshold ≤0.3 V). Tie to VIN or leave open if unused. An RC network on this pin can implement soft-start. Absolute max: -0.3 V to (VIN+0.3 V), <45 V.
5 VIN power_in Power input voltage pin. Operating range 4.5 V to 42 V; absolute max +45 V. Bypass locally with an input capacitor (CIN) to GND.
6 SW power_out Power FET switching output. Connect to the external inductor, catch diode, and CBOOT bootstrap capacitor. Rated up to 42 V; internal switch RDSON ≈ 0.9 Ω typical; current limit ≈ 1.15 A typical.

Ordering variants

Same part, different packaging or reel option.

  • LMR14206XMKX

CAD (KiCad official)

  • Symbol: LMR14206XMKX
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: lmr14206xmkx-etched.step / lmr14206xmkx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lmr14206xmkx.step / lmr14206xmkx.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lmr14206xmkx.step 97 KB You want the bare part, or you mark your own boards.
lmr14206xmkx-etched.step 2.0 MB You want the part with LMR14206XMKX already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 512 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.

Provenance

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