XL4005E1

by XLSEMI(芯龙)

Building a step-down switching supply around the XLSEMI XL4005E1 starts with a buck regulator IC and the surrounding power components. The device is intended for converting a higher DC supply into a lower output voltage. This library entry uses the surface-mount TO-263-5_L10.2-W9.2-P1.70-TL footprint. Although the package name includes five leads, the supplied footprint has six pads and the symbol has six pins. Both are included in the free KiCad download alongside a 3D model. The conversion comes from a real ProtoFlow import and was checked in the editor. Open the regulator directly in ProtoFlow to work with these files.
