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 NMOS boost switch. Connect the boost inductor and Schottky rectifier here. LX can swing between GND and 30V. |+| 2 | GND | power_in | Device ground. Connect to a solid ground plane for heat sinking and noise protection. |+| 3 | FB | input | Feedback input regulated to 0.25V (typ, 237-263mV). Connect the low side of the LED string current-sense resistor (R1 = 0.25V / ILED) to this pin. Input bias current is typically −10nA. |+| 4 | EN | input | Enable / PWM dimming control input. Logic high (>1V typ) enables the converter; logic low shuts it down (IIN < 1µA). Also accepts a PWM signal for LED brightness dimming; suggested PWM frequency ≥1kHz or ≤200Hz. Tie to VIN for automatic startup when unused. |+| 5 | OVP | input | Over-voltage protection sense input. Monitors the boost output for open-circuit / open-LED conditions; the converter stops switching when OVP reaches ~35V (typ). Connect to the top of the LED string / output rail. |+| 6 | IN | power_in | Input supply pin, 2.5V-5.5V. Must be locally bypassed with a ceramic capacitor (1µF X5R/X7R recommended) close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | RYCHIP |+| Package | SOT-23-6 |+| Category | LED-drv |+| Pins | 6 |++## Ordering variants++- `RY3730`++## CAD (KiCad official)++- Symbol: `RY3730`+- 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/ry3730-datasheet.pdf) (7 pp, sha256 `b321309d15988426`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
