... Figure 13: Top Layer of Engineering Board (Top View). Recommendation 1: Input and output filter capacitors should be placed on the same side of the PCB, and as close to the EN23F0QI package as possible. They should be connected to the device with very short and wide traces. Do not use thermal reliefs or spokes when connecting the capacitor pads to the respective nodes ...

... Only the thermal pad and the perimeter pads are to be mechanically or electrically connected to the PC board. The PCB top layer under the EN23F0QI should be clear of any metal (copper pours, traces, or vias) except for the thermal pad. The “shaded-out” area in Figure 14 represents the area that should be clear of any metal on the top layer of the PCB ...
