GC2269 from Gcore, 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	Device ground reference.
2	FB	input	Feedback input. PWM duty cycle is set by the combination of FB and SENSE. Internal impedance ~7.2 kOhm; open-pin voltage ~6.0 V; zero-duty threshold ~0.95 V; burst-mode threshold ~1.7 V; overload (OLP) threshold ~4.7 V.
3	VIN	input	High-voltage line sensing / startup input. Connects through a large resistor and filter to the bulk rail, and works with VDD to bias the IC at startup (used for OCP threshold line compensation).
4	RI	input	Internal oscillator frequency-setting pin. A resistor from RI to GND programs the PWM switching frequency (typ 65 kHz at RI = 24 kOhm). RI range 12-60 kOhm; RI_Open ~2.0 V.
5	RT	input	Temperature-sense input for OTP. Connect an NTC resistor from RT to GND; RT sources ~70 uA. OTP triggers at Vth_OTP ~1.065 V (150 degC); RT open voltage ~4.7 V.
6	SENSE	input	Current-sense input from the MOSFET source resistor. Internal input impedance ~30 kOhm; leading-edge blanking ~250 ns; OCP threshold ~0.90 V (uncompensated), ~0.81 V (compensated). Also labeled 'CS' on the pin-out diagram.
7	VDD	power_in	IC supply pin. UVLO enter/exit thresholds ~10.5 V / ~16.5 V; internal clamp ~35 V; OVP turn-on ~25 V, turn-off ~23 V. Startup current ~5.8 uA, operating current ~2.3 mA.
8	GATE	output	Soft gate-drive output for the external power MOSFET. VOH >= 11 V at 20 mA, VOL <= 0.3 V at 20 mA, clamped to ~18 V. Rise ~120 ns / fall ~50 ns into 1 nF.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`gc2269.step`	122 KB	You want the bare part, or you mark your own boards.
`gc2269-etched.step`	1.8 MB	You want the part with `GC2269` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 415 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.
