I am trying to source (hopefully) a single power supply for my present project. From this single source I was thinking of using appropriate buck and boost converter circuits to fan out the various voltages I need.
I understand that with something like a basic DC voltage regulator, your 'excess' is basically dissipated by heat (which you have to watch out for/ensure to control).
Seeing with almost everything in engineering there is inevitably a 'trade off', I was wondering what the case was in terms of 'buck and boost' ?
For one, from some circuits I have looked at, I can obviously see they don't have 100% efficiency (though many are not all that bad)-- Though at the same time with the right IC these circuits are much simpler than the straight 'power/transformer' circuitry that would otherwise be needed.
In this sense, I am wondering what is the 'cost' of buck and boost-- is heat still a major issue ? Is it only a matter of a certain loss of efficiency ?
A bit of a basic question I know, but still trying to wrap my head around this.
