... The input and output filter capacitors should be placed as close to the Recommendation 1: EP5388QI as possible to reduce EMI from input and output loop AC currents. This reduces the physical area of these AC current loops. Recommendation 2: The system ground plane should be the first layer immediately below the surface layer (PCB layer 2) ...
