XL4015E1
by XLSEMI(芯龙)
Stepping a DC supply down to a lower regulated rail is the job of the XLSEMI XL4015E1 buck regulator. It belongs in a switching power stage with the surrounding energy-storage, filtering, and feedback components chosen for the application. The supplied package is surface-mount TO-263-5, while the converted library contains six symbol pins and six footprint pads. Both counts are preserved in the free KiCad download, which includes the symbol, TO-263-5_L10.2-W8.9-P1.70-TL footprint, and a 3D model for examining placement in the board assembly. In real designs, 1 ProtoFlow engineer has used this conversion. The regulator can be opened directly in ProtoFlow.
