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 pin. Common return for the internal control circuitry and low-side power MOSFET. |+| 2 | CS | input | Output current sense input. The chip regulates the voltage on this pin to a 0.22 V reference (±3%), setting LED current as IOUT = 0.22 V / RCS. Absolute maximum voltage on this pin is 7 V. |+| 3 | SW | output | Power switch output - switching node of the internal synchronous buck converter. Connects to the external inductor. High-side RDS(ON) ≈ 270 mΩ, low-side RDS(ON) ≈ 255 mΩ, current limit ≈ 2.2 A. Also electrically connected to the TO263-5L metal tab. |+| 4 | VC | passive | Internal voltage regulator bypass capacitor pin. A 1 µF ceramic capacitor must be connected between VIN and VC to decouple the internal LDO/bias supply. |+| 5 | VIN | power_in | Power supply input, DC 5 V to 72 V (absolute max 90 V). An electrolytic bulk capacitor must be placed between VIN and GND to filter input noise; a typical 47 µF/100 V is used in the reference design. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XLSEMI |+| Package | TO-263-5L |+| Category | LED Drivers |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `XL9613`++## CAD (KiCad official)++- Symbol: `XL9613`+- Footprint: `Package_TO_SOT_SMD:TO-263-5_TabPin6`+- 3D model: TO-263-5L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XLSEMI datasheet](docs/xl9613-datasheet.pdf) (None pp, sha256 `9902a53dcb35e9d4`, retrieved 2026-08-17, tier: manufacturer)+- **Datasheet language:** Chinese.
