Layout
Board layout is critical for all switch mode power supplies. Figures 3−1, 3−2,
and 3−3 show the board layout for the HPA023 PWB. 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. Refer to the data sheet for more specific layout guidelines.
