CJ9113T6A from Changjing, in a SOT-23-6L. 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	passive	Switch node. Boost inductor connection between the internal N-channel low-side switch and P-channel synchronous rectifier. Connect the external boost inductor between VIN and this pin. Absolute maximum -0.3 V to 6 V.
2	GND	power_in	Device ground. Return for all internal circuitry and reference for feedback and enable thresholds.
3	EN	input	Enable control input. Logic high (>=70% of VIN) enables the converter; logic low (<=20% of VIN) puts the device into shutdown (typ. 0.6 uA). In the CJ9113T6A shutdown the load is truly disconnected from VIN. Input leakage typ. 5 nA at VEN=5 V. Absolute maximum -0.3 V to 6 V.
4	VFB	input	Feedback voltage input to the internal error amplifier. Regulates to 1.215 V typical (1.179 V to 1.251 V). Connect to the external resistor divider tap from VOUT to set output voltage. Bias current typ. 10 nA. Absolute maximum -0.3 V to 6 V.
5	VOUT	power_out	Regulated boost output voltage. Adjustable from 1.8 V to 5.5 V via the external VFB divider. Also serves as the drain connection for the internal synchronous P-channel rectifier. Bypass with a 10 uF ceramic capacitor to GND. Absolute maximum -0.3 V to 6 V.
6	VIN	power_in	Input supply voltage. Operating range 0.82 V to 5.5 V after start-up (start-up 0.82 V at 1 mA load, minimum operating 0.65 V). Bypass with a 4.7 uF ceramic capacitor to GND. Absolute maximum -0.3 V to 6 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cj9113t6a.step`	97 KB	You want the bare part, or you mark your own boards.
`cj9113t6a-etched.step`	1.8 MB	You want the part with `CJ9113T6A` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 433 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.
