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 | FB | input | Feedback pin. Internal feedback threshold voltage is 5 V; connect directly to the regulated output to close the loop for the fixed 5 V output. |+| 2 | NC | unconnected | No connect. Leave floating. |+| 3 | VC | passive | Internal voltage regulator bypass capacitor pin. Connect a 1 uF (105) capacitor from VC to VIN to bypass the internal regulator. |+| 4 | VIN | power_in | Supply voltage input, 8 V to 45 V DC operating range (absolute max 50 V). Bypass to GND with a suitably large capacitor (e.g. 47 uF/50 V) to eliminate input noise. |+| 5 | SW | output | Power switch output. Drain of the internal high-side power MOSFET (Rdson ~60 mohm typ); connects to the external inductor and catch (Schottky) diode of the buck converter. Pins 5 and 6 are tied together internally. |+| 6 | SW | output | Power switch output (paralleled with pin 5) for current-handling and thermal reasons. Connects to the external inductor and catch (Schottky) diode. |+| 7 | GND | power_in | Ground return. Route outside the schottky-diode-to-output-capacitor ground path to prevent switching current spikes from injecting noise into the IC. Pins 7 and 8 are tied together internally. |+| 8 | GND | power_in | Ground return (paralleled with pin 7). Careful layout required; keep out of the high-di/dt loop between the catch diode and output capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XLSEMI |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `XL2011E1`++## CAD (KiCad official)++- Symbol: `XL2011E1`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XLSEMI datasheet](docs/xl2011e1-datasheet.pdf) (10 pp, sha256 `1d61a5df07a0d005`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
