Reading textbooks on linear ICs and Switching power supplies, I am confused which one is better as far as the quality of the output is concerned regardless of efficiency etc.
The book mentioned that certain applications cannot accept current in bursts as the Switching power supplies deliver...
However, I guess the output is satisfactory with high frequencies and a proper low pass filter.
However a computer running at a few GHz might not be able to tolerate ripples in it's power supply....(my guess)...But all computers have SMPS....What is the trick here.
Is SMPS a compromise between quality and efficiency? or does it have an absolute edge over linear regulators?
