TPS560430XDBVR 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 connection for the high-side FET driver. Connect a high-quality 100-nF capacitor from this pin to the SW pin. Absolute max CB-to-SW = 5.5 V.
2	GND	power_in	Power ground terminal, connected internally to the source of the low-side FET. Connect to system ground and to the ground side of C_IN and C_OUT; path to C_IN must be as short as possible.
3	FB	input	Feedback input to the converter. Connect a resistor divider from V_OUT to set the output voltage (V_REF = 1.00 V typ; fixed 3.3-V variant uses V_REF = 3.3 V). Never short this terminal to ground during operation.
4	EN	input	Precision enable input. Do not float. High = on (V_EN_H ~1.23 V), Low = off (V_EN_L ~1.1 V); can be tied to VIN. Adjustable UVLO can be implemented via an external resistor divider. Absolute max = VIN + 0.3 V.
5	VIN	power_in	Supply input terminal to the internal bias LDO and high-side FET. Operating input range 4 V to 36 V (absolute max 38 V). Connect input bypass capacitors C_IN directly between this pin and GND.
6	SW	output	Switching output of the converter. Internally connected to the source of the high-side FET and the drain of the low-side FET. Connect to the power inductor. Supports up to 600-mA continuous output current.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tps560430xdbvr.step`	97 KB	You want the bare part, or you mark your own boards.
`tps560430xdbvr-etched.step`	2.8 MB	You want the part with `TPS560430XDBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 678 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.
