In Part 2-1 of our Power Supply Design
Tutorial we’re going to start a deep-dive into the buck converter and
select one very important part, the output inductor. Then, we’ll begin
with the design philosophy for the input capacitors. The output
inductor, or the buck inductor, is the key piece of this and nearly
every other switching regulator…
