XL2011E1

XLSEMI · DC-DC Converters · SOIC-8

XL2011E1 from XLSEMI, in a SOIC-8. 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.
