HG2263M6 from HGSEMI, 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 IC.
2	FB	input	Feedback input pin. Input impedance ~20 kΩ; FB open-loop voltage ~4.7 V. Used to close the PWM loop for output regulation.
3	RI	input	Programs the switching frequency by connecting a resistor to GND (operating RI range 50-150 kΩ; 100 kΩ gives ~65 kHz).
4	CS	input	Current sense input, connected through a resistor to GND to set the primary side peak current. Current limiting threshold ~0.80 V (zero duty cycle).
5	VDD	power_in	IC DC power supply input. Recommended operating range 10-34 V; startup threshold ~17 V, shutdown threshold ~8 V; OVP at ~35 V; absolute max 38 V.
6	GATE	output	Totem-pole gate driver output for the external power MOSFET. Gate clamp ~13.5 V; typical rise/fall 260/70 ns into 1 nF.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`hg2263m6.step`	97 KB	You want the bare part, or you mark your own boards.
`hg2263m6-etched.step`	1.9 MB	You want the part with `HG2263M6` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 456 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.
