WHEN IS IT BENEFICIAL TO PLACE A COPPER LAYER BENEATH DC/DC POWER SUPPLIES?
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...
