That's why I mentioned it.

I don't know. Since I do not have a successful ball-grid challenge
under my belt
I usually don't look at parts in ball-grid packages ;-)  (or QFN's!)

For buck converters I have been using the LT1616. The LT1933 is lower frequency
but has the same pinout. Both are in SOT23-6 packages.
