All the switching regulators I use have to be cheap (and small=20
footprint, which may not apply to you), and for this I like the National=20
(yeah, I'm not calling it TI on purpose :) Simple Switchers.  They're a=20
couple bucks or so each, but at anywhere from 500kHz to >1Mhz, the=20
passives get really small, and hence cheaper, which very much offsets=20
the price of the switching chip itself.  And the number of external=20
components are quite small.

Cheers,
