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 controller and internal power MOSFET source. Tied together with pin 2 internally. |+| 2 | GND | power_in | Ground reference for the controller and internal power MOSFET source. Tied together with pin 1 internally. |+| 3 | NC | unconnected | No connect. Should be left floating or connected to GND during normal operation. |+| 4 | VDD | power_in | Controller power supply and output voltage feedback pin. Internally regulated to ~12.1V average; UVLO_ON ≈7.0V (falling), UVLO_OFF ≈13.5V (rising), OVP ≈17.5V. Operating range 8 to 12V; absolute max 18V. |+| 5 | Drain | power_in | Drain of the internal 650V power MOSFET. Pins 5/6/7/8 are tied together to share current and improve thermal dissipation. Rdson ≈9Ω (OB2235N). |+| 6 | Drain | power_in | Drain of the internal 650V power MOSFET (tied to pins 5/7/8). |+| 7 | Drain | power_in | Drain of the internal 650V power MOSFET (tied to pins 5/6/8). |+| 8 | Drain | power_in | Drain of the internal 650V power MOSFET (tied to pins 5/6/7). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | OB On Bright Elec |+| Package | SOP-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `OB2235NCPA-HNCP-H`+- `OB2235NCPA-H`+- `OB2235NCPA-HNAP-H`+- `OB2235NCPA-HRAP-H`+- `OB2235NCPA-HNASP-H`+- `OB2235NCPA-HRASP-H`++## CAD (KiCad official)++- Symbol: `OB2235NCPA-H`+- 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/ob2235ncpa-h-datasheet.pdf) (12 pp, sha256 `d3bc0bc6f818db01`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
