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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | OB On Bright Elec |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `OB2269CCPACCP`+- `OB2269CCPACCPV`+- `OB2269CCPACAP`+- `OB2269CCPACAPV`++## CAD (KiCad official)++- Symbol: `OB2269CCPA`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [OB On Bright Elec datasheet](docs/ob2269ccpa-datasheet.pdf) (13 pp, sha256 `8868587f1ead77b4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
