Source interaction with board-mount converters

Dr. Ray Ridley, President, Ridley Engineering

Board-mount power supplies use multilayer ceramics for both their input and output capacitors. The inherently low ESR values lead to transfer functions with higher Q than converters using electrolytic capacitors, and this can lead to interesting effects when making measurements. Many newcomers to the field
