Apparently, switched-mode power supplies are quite hard to get right.
How many of these problems (such as oscillations/stability concerns) generally remain when using off-the-shelf DC/DC converter ICs?
What I'm aiming to do is to use two regulators, one DC/DC switched-mode and one linear, to convert a ~22-24 VDC input to an adjustable (0 - ~18 V, perhaps) PSU. The purpose of the switcher would then be to increase efficiency for the lower output voltages (for e.g. 5 V output, (22-5) = 17 W/A of heat for a linear regulator isn't very nice), and to improve the noise figures.
As far as my knowledge/experience is concerned, I've learned a ton from a proper intro course the past 3 months, so I'm a bit embarrassed by my previous postings here at this point.
Still, despite basic coverage of a wide range of topics, I'm obviously not a pro from one course.
As for specific knowledge on this topic, I understand the basics of how switched-mode supplies operate, but not a whole lot more.
I'm willing to learn more, of course - if it's a manageable amount of information to take in, i.e. a lot less than the full design of an proper SMPS from scratch.
