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 | GND | power_in | Ground return for the device. Connect to a large copper area for thermal dissipation and to minimize the power loop with the input capacitor and internal MOSFETs. |+| 2 | SW | output | Switching node output; the common drain of the internal high-side and low-side power MOSFETs. Connect to the external inductor. Rated -0.3V to (VIN+0.5V). |+| 3 | IN | power_in | Power supply input, 4V to 18V (absolute max 21V). Bypass with a ceramic input capacitor placed close to the pin. |+| 4 | FB | input | Feedback input for the adjustable output. Connect to the center tap of an external resistor divider from VOUT to GND. Regulated to 0.768V typical (0.749V to 0.787V over temperature). Absolute max -0.3V to 6V. |+| 5 | EN | input | Enable input. Drive logic-high (rising threshold typ 1.15V) to enable the IC; drive logic-low to enter micro-power shutdown (typ 10µA). Absolute max -0.3V to 21V. |+| 6 | BS | passive | Bootstrap pin for the high-side gate driver. Connect a bootstrap capacitor between SW and BS to form the floating supply that drives the high-side MOSFET. Rated (VSW-0.3V) to (VSW+5V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | RYCHIP |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `RY3825`++## CAD (KiCad official)++- Symbol: `RY3825`+- 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/ry3825-datasheet.pdf) (9 pp, sha256 `578aea52c47ad414`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
