HG2269M from HGSEMI, in a SOP-8. 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. All internal analog and logic returns tie to this pin.
2	FB	input	Feedback input pin. PWM duty cycle is determined by the voltage on this pin combined with the current-sense signal at Pin 6 (SENSE). Typically driven by an optocoupler.
3	VIN	input	High-voltage startup / line-sensing input. Connected through a large-value resistor to the rectified line input for startup IC supply and line voltage sensing. Rated up to 30V.
4	RI	input	Internal oscillator frequency-setting pin. A resistor connected between RI and GND sets the PWM switching frequency (recommended 24-31 kOhm).
5	RT	input	Temperature-sensing input pin. Connected through an NTC resistor to GND for external over-temperature protection.
6	SENSE	input	Current-sense input. Connected to the MOSFET source current-sensing resistor node for cycle-by-cycle over-current protection and PWM regulation. Leading-edge blanking is applied internally.
7	VDD	power_in	DC power supply pin. Recommended operating range 12-23V, absolute max 30V (clamp 35V). Bypass with local capacitor to GND.
8	GATE	output	Totem-pole gate-drive output for the external power MOSFET. Output is internally clamped at 18V to protect the MOSFET gate.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`hg2269m.step`	122 KB	You want the bare part, or you mark your own boards.
`hg2269m-etched.step`	1.8 MB	You want the part with `HG2269M` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 432 faces against 147 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.
