TP8204HS6 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 reference for the converter. Connect to the system ground plane with a low-impedance path; the input and output capacitor return currents should be tied here.
2	LX	output	Switching node connecting the drains of the internal high-side and low-side MOSFETs. Connect the external inductor from LX to VOUT. Absolute maximum voltage on LX is -0.3V to 20V.
3	IN	power_in	Power supply input pin (VIN). Accepts 3.5V to 18V input; bypass with a low-ESR ceramic capacitor (typ. 22uF) placed close to the pin. Absolute maximum 20V.
4	FB	input	Feedback input for output voltage regulation. Connect to the center tap of an external resistor divider from VOUT to GND; regulated to VFB = 0.8V (typ). Absolute maximum -0.3V to 6.0V.
5	EN	input	Enable input. Drive high (>=1.5V) to enable the IC; drive low (<=0.5V) to disable and enter micro-power shutdown (~1uA). Do not leave floating.
6	BS	passive	Bootstrap pin for the high-side gate driver. Connect a ceramic bootstrap capacitor between LX and BS to form a floating supply for driving the high-side switch. Absolute maximum -0.6V to 25V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tp8204hs6.step`	97 KB	You want the bare part, or you mark your own boards.
`tp8204hs6-etched.step`	2.0 MB	You want the part with `TP8204HS6` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 489 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.
