XL6003E1 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 EN input Enable pin. Drive low (<=0.8 V) to shut down the regulator; drive high (>=1.4 V) to enable. Floats high by default. TTL-compatible.
2 VIN power_in Supply voltage input, 3.6 V to 24 V DC (abs max 26 V). Bypass to GND with a suitably large ceramic/electrolytic capacitor (typ 47 uF) to eliminate input noise.
3 FB input Feedback pin. The internal reference regulates this pin to 0.22 V (typ, 209-231 mV). LED current is set by ILED = 0.22 V / RS where RS is the sense resistor from the LED cathode to GND.
4 NC unconnected No connect. Leave floating or tie to GND.
5 SW output Power switch output. Drain of the internal N-channel power MOSFET (Rds(on) ~110 mohm, 2 A switch current limit, 60 V abs max). Connect to the boost inductor and Schottky rectifier. Pins 5 and 6 are tied together internally for higher current handling.
6 SW output Power switch output (parallel with pin 5). Connect together with pin 5 to the switching node.
7 GND power_in Ground pin. Tie to pin 8 and to the input bypass capacitor and sense resistor return. Also acts as thermal return path for the SOP-8 (RJA = 100 degC/W).
8 GND power_in Ground pin (parallel with pin 7). Connect together with pin 7 to the system ground.
