TPS40055-EP: need clarification of which footprint on the datasheet is correct

Hello,

I have a customer who identified that there are two different footprints at the end of the datasheet where the differences have to do with the exposed pad under the IC. They are similar in size, but 90 degrees from each other.

Can you please help clarify which footprint is correct when you order the part?

There is PWP0016C and PWP0016K.

Thanks,

Kevin
