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 | BS | passive | Bootstrap. A capacitor connected between SW and BS pins forms a floating supply across the high-side switch driver. Absolute max BS voltage is Vsw+5V. |+| 2 | GND | power_in | Ground pin. Common return for the IC and the low-side power MOSFET. |+| 3 | FB | input | Adjustable version feedback input. Connect FB to the center point of the external resistor divider that sets VOUT via VOUT = VFB × (R1+R2)/R2, where VFB = 0.6V typical. Absolute max FB voltage is 6V. |+| 4 | EN | input | Enable input. Drive high (≥1.4V typ.) to enable the IC; drive low (≤0.8V typ.) to disable and enter micro-power shutdown mode. Absolute max EN voltage is 18V. |+| 5 | IN | power_in | Power supply input. Operating range 4.5V to 17V; absolute max 18V. Bypass with a ceramic capacitor placed as close as possible to this pin. |+| 6 | SW | power_out | Switching node. Connects to the external inductor. Internal high-side (70mΩ) and low-side (50mΩ) MOSFETs switch this node between IN and GND. Absolute max SW voltage is VIN+0.5V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | RYCHIP |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `RY9131ECYLL`++## CAD (KiCad official)++- Symbol: `RY9131`+- 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:** [RYCHIP datasheet](docs/ry9131-datasheet.pdf) (13 pp, sha256 `8e57144f069ec4a8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
