LMR14010ADDCR 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 for the high-side switch FET gate bias. Connect a Cboot capacitor between CB and SW. CB-to-SW absolute max 7 V; recommended CB-to-SW up to 6 V.
2	GND	power_in	Ground connection. Reference for all internal circuitry and the return path for input and output currents.
3	FB	input	Feedback pin. Set the output voltage with a resistor divider using VOUT = VFB * (1 + R1/R2), where VFB = 0.765 V (typ). Absolute max -0.3 V to 7 V; recommended 0 V to 5 V.
4	SHDN	input	Active-low enable/shutdown input (high-voltage tolerant, up to 45 V abs max). Has an internal pull-up current source; float to enable, pull below 1.25 V (typ rising threshold) to disable. Can be driven from a resistor divider on VIN for programmable input UVLO.
5	VIN	power_in	Power input voltage pin. Supplies internal bias and is the drain of the internal high-side MOSFET. Recommended operating range 4 V to 40 V; absolute max 45 V. Bypass with a local ceramic input capacitor to GND.
6	SW	output	Switch node output. Connect to the power inductor, the freewheeling (catch) diode cathode, and the Cboot capacitor. Recommended operating range -0.7 V to 40 V; up to 1 A continuous.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmr14010addcr.step`	97 KB	You want the bare part, or you mark your own boards.
`lmr14010addcr-etched.step`	2.2 MB	You want the part with `LMR14010ADDCR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 551 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.
