OB2269CCPA from OB On Bright Elec, 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.
2	FB	input	Feedback input pin. PWM duty cycle is determined by voltage level into this pin and current-sense signal level at Pin 6 (SENSE). Input impedance ~7.2 kOhm; VFB open voltage ~5.9 V; power-limiting threshold ~4.4 V; burst-mode threshold ~1.7 V.
3	VIN	input	High-voltage line-sense/startup input. Connected through a large value resistor to the rectified line input for startup IC supply and line voltage sensing (feeds OCP threshold line compensation). Absolute max 30 V.
4	RI	input	Internal oscillator frequency setting pin. A resistor connected between RI and GND sets the PWM switching frequency. Recommended RI resistor value 24-31 kOhm.
5	RT	input	Temperature sensing input pin for external programmable over-temperature protection (OTP). Connected through an NTC resistor to GND. Absolute max -0.3 to 7 V.
6	SENSE	input	Current sense input pin. Connected to the MOSFET current sensing resistor node. Provides cycle-by-cycle current limiting with 250 ns leading-edge blanking; input impedance ~30 kOhm. Absolute max -0.3 to 7 V.
7	VDD	power_in	DC power supply pin. Recommended operating range 12-23 V; UVLO enter ~10.5 V, UVLO exit (startup) ~16.5 V; optional OVP ~25 V; internal Zener clamp ~35 V (max clamp current 10 mA). Startup current ~6.5 uA, operating current ~2.3 mA.
8	GATE	output	Totem-pole gate drive output for the external power MOSFET. Output is clamped at 18 V to protect the power MOSFET gate. Driven by the internal soft driver with frequency shuffling for improved EMI.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ob2269ccpa.step`	122 KB	You want the bare part, or you mark your own boards.
`ob2269ccpa-etched.step`	2.4 MB	You want the part with `OB2269CCPA` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 560 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.
