To maximize the efficiency of this package for application on a single layer or multi-layer PCB, certain guidelines
must be followed when laying out this part on the PCB.
5.1.
The following are guidelines for mounting the exposed pad ZSPM4551 on a multi-layer PCB with ground a plane.
In a multi-layer board application, the thermal vias are the primary method of heat transfer from the package
thermal pad to the internal ground plane. The efficiency of this method depends on several factors, including die
area, number of thermal vias, and thickness of copper, etc.
