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 | SW | power_out | Switching node. Drain of the internal 4A power NMOS. Connect to the boost inductor and Schottky diode (e.g., SS34). Abs max Vss-0.3 to Vss+28V; leakage 1uA typ at VSW=20V. High-frequency node; keep traces short and isolated. |+| 2 | GND | power_in | Ground/return reference for the IC (Vss). Connect directly to the system ground plane near input/output capacitors. |+| 3 | FB | input | Feedback input to the error amplifier. Internal reference VFB = 0.6V (typ, 588-612 mV). Output voltage set by external divider: VOUT = 0.6V x (1 + R1/R2); R1 in the hundreds of kΩ. |+| 4 | EN | input | Chip enable input, active high. VENH >= 1.2V (enable), VENL <= 0.4V (shutdown). Shutdown current IOFF ~0.01uA (1uA max) when VEN < VENL. |+| 5 | VIN | power_in | Supply input. Operating range 2-24V; abs max Vss-0.3 to Vss+24V. UVLO falling ~1.7-2V with ~100mV hysteresis. Decouple with >=22uF close to the pin. |+| 6 | NC | unconnected | No connect. Leave floating (datasheet: 悬空). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HXY MOSFET |+| Package | SOT-23-6L |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `HFP6291LR-G1LR-G1`++## CAD (KiCad official)++- Symbol: `HFP6291LR-G1`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HXY MOSFET datasheet](docs/hfp6291lr-g1-datasheet.pdf) (6 pp, sha256 `e136b6fd95a93370`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
