UNDERSTANDING POWER INDUCTOR PARAMETERSARTICLE
Modern DC/DC converter demands are largely driven by consumer applications. These applications require power inductors mainly for battery-powered devices, embedded computing, and high-power/frequency DC/DC converters. It is essential to understand the electrical characteristics of inductors to design systems that are compact, cost-effective, efficient, and provide excellent thermal performance. I...

WHEN IS IT BENEFICIAL TO PLACE A COPPER LAYER BENEATH DC/DC POWER SUPPLIES?ARTICLE
Engineers often disagree on whether the inductive bottom of DC/DC power supplies should be laid with copper. The first argument is that laying copper under the inductor produces eddy currents on the ground plane. As a result, the eddy current affects the power inductor’s inductance and increases the system loss, and the ground plane noise impacts other high-speed signals. The second argument is th...
