EN5336QI
Only the large thermal pad and the perimeter pads are to be mechanically or electrically connected to
the PC board. The PCB top layer under the EN5336QI should be clear of any metal except for the
large thermal pad. The “grayed-out” area in Figure 4 represents the area that should be clear of any
metal (traces, vias, or planes), on the top layer of the PCB.
