... Figure 4. V (POK) indicating Input Capacitor Selection and the OVP trip The EN5366QI requires about 40-50uF of input capacitance. Low ESR ceramic capacitors are required with X5R or X7R dielectric formulation. Y5V or equivalent dielectric formulations must not be used as they lose capacitance with frequency, temperature and bias voltage. ...

... 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 EN5366QI should be clear of any metal except for the large thermal pad. The “grayed-out” area in Figure 7 represents the area that should be clear of any metal (traces, vias, or planes), on the top layer of the PCB ...
