The GND pin should be tied directly to the PowerPAD under the IC. The PowerPAD should be connected to any
internal PCB ground planes using multiple vias directly under the IC.
It may be possible to obtain acceptable performance with alternate PCB layouts; however, the layout shown in
Figure 33 and the schematic shown in Figure 34 have been shown to produce good results and are meant as a
guideline.
