LM2576HVS-12
Public Made by Adomby adom
TECH PUBLIC DC-DC Converters, TO-263-5L. Pinout extracted from the datasheet, KiCad symbol/footprint/3D.
← Commit history
add symbol pin "6" for the exposed thermal pad: the footprint carries the pad and the symbol had none, so it reached no net (vendor string 'TO-263-5L' states 5 pins and the footprint has exactly one more pad, so it is the tab)
