That is true. In terms of power conversions, Linear Tech is still the king. National is good -- relative small package, cheaper, and normally good enough, but just not good enough sometimes. TI is also catching up. ADI is very good in other part of analog (especially data converter) but lag far behind in the power conversion section. Maxim is quite all around but can not beat Linear Tech in power conversion side. Intersil is very good at VRMs for PCs. Semtech, Fairchild, OnSemi and some other companies have some good parts as well.
