TMI3341 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	BS	passive	Bootstrap pin. A capacitor (typ. 0.1µF) connected between LX and BS forms a floating supply for the high-side MOSFET gate driver.
2	GND	power_in	Ground pin. Device ground return for all internal circuitry and the low-side MOSFET.
3	FB	input	Output voltage feedback input. Connect to the center tap of the external resistor divider from VOUT. Internal reference VFB = 0.8V ±2%.
4	EN	input	Enable input. Drive logic-high to enable the IC, logic-low to disable and enter micro-power shutdown. EN rising threshold ~1.1V; do not leave floating. Max VEN = VIN.
5	IN	power_in	Power supply input, 4.5V to 30V (abs max 32V). Bypass with a low-ESR ceramic capacitor (e.g. 22µF + 100nF) close to the pin.
6	LX	power_out	Switching node. Common drain of the internal high-side and low-side power MOSFETs; connects to the external inductor and the bootstrap capacitor. Rated 1.2A continuous output current.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tmi3341.step`	97 KB	You want the bare part, or you mark your own boards.
`tmi3341-etched.step`	1.4 MB	You want the part with `TMI3341` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 355 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.
