XDS DC-DC Converters, SOP-8. Pinout extracted from the datasheet, KiCad symbol/footprint/3D.

page.json: drop the phantom "EP" pin. The datasheet package drawing is a plain SOP-8 - the datasheet carries no package outline drawing at all, its own application BOM lists the IC as SOP-8, and LCSC stocks TX4151 as SOP-8 while listing its siblings TX4138 as SOIC-8-EP and TX4150A as ESOP-8, so the family is mixed and the sibling packages say nothing about this part, matching the shipped footprint exactly, so there is no exposed pad for this entry to describe and no symbol pin could ever resolve to it. Removed rather than "fixed" by adding a pad: putting copper under a part whose die has no thermal path would be the real defect.
