9. Inductor Basics
Question.1
Shantanu is repairing a DC-DC buck converter that originally used a 10 µH power inductor rated for 3 A.
Unable to source the original part quickly, he substitutes it with a ferrite bead of similar size, rated 120 Ω @ 100 MHz, 3 A max.
After powering up, the converter fails to regulate properly.
What is the most likely reason?
