TPMP1470GJ-Z from TECH PUBLIC, 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	GND	power_in	Ground return. Connect to the system ground plane with a low-impedance path to the input and output capacitors.
2	LX	output	Switching node. Internal high-side and low-side MOSFET common drain output. Connect to the external inductor. Absolute max VLX = -0.3 to 20V.
3	IN	power_in	Power supply input pin. 3.5V to 18V operating range (Vcc absolute max 20V). Bypass with a 22 uF ceramic capacitor close to the pin.
4	FB	input	Adjustable version feedback input. Connect FB to the center point of the external resistor divider from VOUT. Regulated to VFB = 0.8V typ (0.784-0.816V). Absolute max -0.3 to 6.0V.
5	EN	input	Enable / shutdown input. Drive high to enable the IC; drive low to disable and enter micro-power shutdown mode (~1 uA). Absolute max 20V.
6	BS	passive	Bootstrap pin. A capacitor connected between LX and BS forms a floating supply for the high-side switch driver. Absolute max -0.6 to 25V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tpmp1470gj-z.step`	97 KB	You want the bare part, or you mark your own boards.
`tpmp1470gj-z-etched.step`	1.8 MB	You want the part with `TPMP1470GJ-Z` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 461 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.
