4.2 Layout

The TPS92520EVM-133 is a 4-layer board. Figure 4-3, Figure 4-4, Figure 4-5, Figure 4-6 and Figure 4-7 illustrate the assembly, the top, the inner-layer1, the inner-layer2 and the bottom side of the TPS92520EVM-133 PCB layout. The Inner-layer 1 is a ground plane and there is no routing on this layer.
