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 | LX | output | Power switch output. Drain of the internal 0.2Ω, 16V N-channel power MOSFET; connects to the boost inductor and Schottky rectifier. Absolute maximum LX voltage is 16V. |+| 2 | GND | power_in | IC ground. Reference for all internal circuitry and source of the internal power MOSFET. |+| 3 | FB | input | Error amplifier inverting input. Connect a resistor divider from VOUT to set the output voltage; regulates to the internal 0.6V (±2%) precision reference. |+| 4 | EN | input | Enable control, active high. VEN ≥ 0.96V enables the converter; VEN ≤ 0.6V shuts it down (shutdown current 0.1µA typ). Absolute maximum 6V. Do not leave floating. |+| 5 | VCC | power_in | IC power supply input. Operating range 2.6V to 5.5V; absolute maximum 6V. Bypass locally with a ceramic capacitor. UVLO threshold ≈ 2.2V with 0.1V hysteresis. |+| 6 | OC | input | Adjustable current limit. Connect an external resistor (19kΩ to 96kΩ) from OC to GND to program the peak switch current limit from ≈2.5A down to ≈0.5A. With 75kΩ, IOCP is 0.53-0.67A on the FP6291LR-G12 variant. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Advanced Analog Technology FP6291LR G1 |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `FP6291LR-G12LR-G11`+- `FP6291LR-G12LR-G12`++## CAD (KiCad official)++- Symbol: `FP6291LR-G12`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Advanced Analog Technology FP6291LR G1 datasheet](docs/fp6291lr-g12-datasheet.pdf) (11 pp, sha256 `83e8e2ce719b3523`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
