TLV61220DBVR 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	SW	input	Boost and rectifying switch input. Connects to the external inductor between VBAT and the internal synchronous switches. Absolute max voltage 7.5 V.
2	GND	power_in	IC ground connection for logic and power. Reference for all internal circuitry and the return path for the switching current.
3	EN	input	Enable input; drive to VBAT to enable the converter, drive to GND to disable and enter shutdown. VIH = 0.8 x VIN (VIN <= 1.5 V) or 1.2 V (VIN > 1.5 V); VIL = 0.2 x VIN or 0.4 V respectively. Input current 0.1 µA max.
4	FB	input	Voltage feedback for programming the output voltage via an external resistor divider from VOUT. Internal reference VFB = 500 mV (typ). Feedback input current 0.01 µA (typ).
5	VOUT	power_out	Boost converter output. Connect the output capacitor (typ 10 µF) and the feedback divider here. Output voltage range 1.8 V to 5.5 V; overvoltage protection threshold 5.5-7.5 V.
6	VBAT	power_in	Supply voltage input from the battery/source. Operating range 0.7 V to 5.5 V; startup min 0.7 V into >=150 Ω load. Connect input capacitor (typ 10 µF) close to this pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tlv61220dbvr.step`	97 KB	You want the bare part, or you mark your own boards.
`tlv61220dbvr-etched.step`	2.1 MB	You want the part with `TLV61220DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 514 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.
