[Milsurplus] DC-DC Buck/Boost Converter Regulation

[Peter Gottlieb]

That's over-generalizing.  It's not terribly difficult to filter a switcher to 
excellent noise levels.  Even common COTS switchers have noise levels that allow 
for just about any except for the most noise sensitive analog circuitry.  
Consider that most Agilent and Tektronix analog test equipment uses switchers.

However, that comes at a price. The switching is noisy electrically. Generally, use is restricted to digital circuitry, although there may be situations where it would work with linear circuits, but I wouldn't count on it.
