It appears that Intel have decided to pull out of the market and drop the Enpirion range of dc/dc converters:

Enpirion was a start-up who developed a really superb range of efficient dc-dc converters with integrated inductors, and I've designed them into dozens of products over the years. The smaller ones in particular are as easy to use as a linear regulator, but with massively improved efficiency, and basically just solved the problem of "how do I generate X volts for this part?" overnight. No extra board area needed for a separate inductor, no complex stability calculations, no EMC headaches, just lay out the PCB sensibly and they 'just work'.
Enpirion was bought by Altera, who wanted them to provide voltage rails for complex FPGAs. Altera in turn was bought by Intel, and from that point on, there was always a chance that they would simply be deemed commercially uninteresting. Sure enough, seems Intel just can't be bothered with them, and attempts to sell the product line on to Mediatek have fallen through.
Now they're going away I'll need to find an alternative. Sad day.

Does anyone know of any other voltage regulators that can do the same job? They'd need to be physically compact, easy to design with, and ideally have the inductor either built in or clearly specified as an external component.
