4 Board Layout
Board Layout www.ti.com
Board layout is critical for all switch mode power supplies. Figure 2 , Figure 3 , and Figure 4 show the board
layout for the HPA265 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 more specific layout guidelines.
