This section provides the TPS61087EVM board layout and illustrations.
Board layout is critical for all switch-mode power supplies. Figure 2 , Figure 3 , and Figure 4 show the
board layout for the HPA317 PCB. The switching nodes with high-frequency noise are isolated from the
noise-sensitive feedback circuitry, and careful attention has been given to the routing of high-frequency
current loops. See the data sheet for further layout guidelines.
