GROUND PLANE
Place a dedicated PGND copper area beneath the MagI³C Power Module.
Use an array of heat-sinking vias to connect the PGND pad to the ground plane on the bottom PCB layer. If the PCB has
multiple of copper layers, these thermal vias can also be used to make a connection to the heat-spreading ground planes
located on inner layers.
