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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `HG2269MM/TR`+- `HG2269MMM/TR`+- `HG2269MN`++## CAD (KiCad official)++- Symbol: `HG2269M`+- 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:** [HGSEMI datasheet](docs/hg2269m-datasheet.pdf) (14 pp, sha256 `09284e98bcc4c86b`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
