I presume you refer to a programmable switching power supply, with an output compliance range that spans the 1:100 voltage range. Most switching designs make use of some nonlinearities of the inductor, and cannot be made wide-range as you require. One interesting technique (series resonant converter) DOES have this kind of capability, but usually operates at inconveniently high frequencies (your output rectifiers, which will have to hold off 100V or more, will be a problem). See if you can locate Signetics application note AN128 (it's reprinted in the Linear Data Manual, volume 2). John Whitmore
