I'd like to build a bench power supply for prototyping and development work. Most of the benchtop power supply designs I have seen are based around a transformer, rectifier and linear regulator (eg 7805/LM317).
However, I like the idea of keeping it efficient, so am interested in building something switchmode instead.
My work is mainly microcontroller-based, but I mess around with audio stuff from time-to-time too. I'm thinking that a 3-rail design (±15V to 0V adjustable, +5V, up to 1A) would cover most things.
Would the increased ripple voltage of a switchmode power supply make it unsuitable for general-purpose use?
Or, given that I'll be relying on this power supply for a lot of future work, should I stick with the simplicity of a linear regulator design?
