Datasheet at http://www.ti.com/lit/ds/symlink/lm5100a.pdf
Page 2 lists all five available packages, assumed top view, all pin1 in the upper left, all counting counter clock wise.
Mechanical data pages at the end give land patterns for all packages. Drawings DGN and DDA have pins numbered counter clock wise. Drawing NGT for WSON8 is numbered clock wise.
Could you please clarify what I am missing?
