12.1 Layout Guidelines

The pinout of the TAS6424E-Q1 was selected to provide flowthrough layout with all high-power connections on the right side, and all low-power signals and supply decoupling on the left side.

Figure 12-1 shows the area for the components in the application example (see the Section 10.2 section).

The TAS6424E-Q1 EVM uses a four-layer PCB. The copper thickness was selected as 70 µm to optimize power loss.

The small value of the output filter provides a small size and, in this case, the low height of the inductor enables double-sided mounting.

The EVM PCB shown in Figure 12-1 is the basis for the layout guidelines.
