The CAT3643 is offered in three different packages.
The 12-pad TDFN 3mm x 3mm with a max height of
0.8mm is pin-compatible to the Catalyst CAT3603
LED driver. The 12-pad XQFN provides the smallest
footprint with a package size of 2.5mm x 2.5mm and
0.4mm max height. The 16-pad TQFN 3mm x 3mm
with max height of 0.8mm is also offered.
