6 FAQs about [Buck circuit inductive energy storage]

Why do buck regulators use double duty energy storage inductors?

The energy storage inductor in a buck regulator functions as both an energy conversion element and as an output ripple filter. This double duty often saves the cost of an additional output filter, but it complicates the process of finding a good compromise for the value of the inductor.
