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 | LATCH | input | Latch-off input. Pulling this pin up or down latches off the controller. An internal current source allows direct connection of an NTC thermistor for over-temperature protection (OTP). Also used for severe fault detection. |+| 2 | FB | input | Feedback input. An optocoupler collector connected to ground controls the output regulation loop. Internally pulled up through a 20 kΩ resistor to VFB(ref); divided by 5 for the PWM comparator. |+| 3 | CS | input | Current sense input. Senses the primary MOSFET current for current-mode operation via an external sense resistor. Provides overpower compensation adjustment and includes leading-edge blanking (tLEB). |+| 4 | GND | power_in | IC ground reference for all internal circuitry and the return path for the DRV output stage. |+| 5 | DRV | output | Gate drive output for the external power MOSFET. ±500 mA peak source/sink drive capability with internal clamp; absolute max −0.3 to 20 V, ±1000 mA. |+| 6 | VCC | power_in | Controller supply input. Accepts up to 28 Vdc with internal overvoltage detection (VCC OVP). Supplied either from an auxiliary winding or from the internal Dynamic Self-Supply (DSS) sourced through the HV pin. |+| 8 | HV | power_in | High-voltage input. Connects to the bulk capacitor or the rectified AC line and performs start-up current source, Dynamic Self-Supply (DSS), brown-out detection and overpower/HV-sense functions. Absolute max −0.3 to 500 V, ±20 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-7 |+| Category | Power Management (PMIC) |+| Pins | 7 |++## Ordering variants++Same part, different packaging or reel option.++- `NCP1236AD100R2G`+- `NCP1236AD100R2GAD65R2G`+- `NCP1236AD100R2GBD100R2G`+- `NCP1236AD100R2GBD65R2G`+- `NCP1236AD100R2GCD100R2G`+- `NCP1236AD100R2GCD65R2G`+- `NCP1236AD100R2GDD100R2G`+- `NCP1236AD100R2GDD65R2G`++## CAD (KiCad official)++- Symbol: `NCP1236AD100R2G`+- Footprint: `Package_SO:SOIC-8-N7_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-7 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/ncp1236ad100r2-d.pdf) (34 pp, sha256 `6670c1f1d749c73d`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
