A few months ago I used the TPS16630 in a new design. I recently checked on availability of that part and found that it is completely out of stock. Fortunately I can also use the TPS16632 and that part has some availability, but not a lot. Since this is still in the design stage I wanted to check if there are any known or expected issues with future availability of this part. There are several other TI parts I could use instead of this particular one.
