Learning is always good... As I've shared before, back in the 60's I had a technician gig working on a switching PS but back then there were no canned IC solutions. The design I worked on was based around a linear regulator, tricked into being a switcher. ;DPhrazemaster said:True but...isn't that cheating? Fun to learn stuff.
I appreciate all the thoughts gang.
Now several decades later there are many IC switcher solutions to pick from. They almost all come with extensive application notes that can help you size inductors and associated parts. Some even include preferred layouts in the application notes. Perhaps start with a search of available switchers then narrow that search based on your application. Then download some app notes and read them...
