SLOS948 February 2019 TAS6424M-Q1
The pinout of the TAS6424M-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.
The TAS6424M-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 85 is the basis for the layout guidelines.
