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 | power_out | Power switch output. Internal drain of the low-side NMOS and source of the high-side PMOS; connect to the boost inductor. Absolute max 6V. |+| 2 | LX | power_out | Power switch output. Second LX pin, tied internally to pin 1. Connect to the boost inductor switching node. |+| 3 | VIN | power_in | IC power supply input. Operating range 2.4V-4.5V (abs max 6V). Decouple locally to GND. |+| 4 | EN | input | Enable control, active high. VEN >= 0.96V enables the converter; VEN <= 0.6V shuts it down (shutdown current <1μA). Abs max 6V. |+| 5 | GND | power_in | IC signal ground. Reference for the internal analog circuitry. Must be tied to the exposed pad (PGND) at the device. |+| 6 | FB | input | Error amplifier inverting input. Connect to the mid-point of the VOUT feedback divider; regulated to VREF = 0.6V (±2%). Abs max 6V. |+| 7 | OC | input | Adjustable current-limit programming pin (floating available). A resistor to GND sets the internal switch current limit (default typ. 6A); leave floating to use the internal default. Abs max 6V. |+| 8 | VO | power_in | Output voltage sense pin. Connect to the boost output rail; used internally to power the high-side driver bulk-well switch via a VO/VIN MUX. Abs max 6V. |+| EP | PGND | power_in | Exposed thermal pad and IC power ground. Must be soldered to the PCB ground plane and connected to GND (pin 5) for proper operation and heat dissipation. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Advanced Analog Technology |+| Package | SOP-8-EP |+| Category | PMIC |+| Pins | 9 |++## Ordering variants++- `FP6276BXR-G1XR-G1`++## CAD (KiCad official)++- Symbol: `FP6276BXR-G1`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8-EP (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Advanced Analog Technology datasheet](docs/fp6276bxr-g1-datasheet.pdf) (12 pp, sha256 `f46290e35f85966e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
