Public Made by Adomby adom
XLSEMI DC-DC Converters, TO-220-5. Pinout extracted from the datasheet, KiCad symbol/footprint/3D.

footprint: the datasheet shows TO220-5L - 5 leads at 1.71mm pitch, matching the symbol's 5 pins - on a 3-pad TO-220-3 footprint. Chosen from this part's OWN datasheet, not inferred from a sibling - the Richtek SOP-8-EP parts alone carry three different exposed-pad sizes, so family inference would have been wrong. Rebuilds the .lbr, re-derives pin 1 and pads.json.
