Yes, you do need a quiet supply -- I suppose I should have mentioned
that. But sufficiently quiet supplies are not hard to design,
they're just more complex than the "has to be done with just one
ten-cent part" crowd wants (don't expect to use integrated regulators
of any description).
Bruce -- do you know the topology of the Holzworth converter?
