Board Layout
3 Board Layout
Board layout is critical for all switch mode power supplies. Figure 6, Figure 7, and Figure 8 show the board
layout for the HPA283 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.
