3.1 Layout
Board Layout
Board layout is critical for all switch-mode power supplies. Figure 1 through Figure 5 show the board
layout for the TPS65021EVM-110 printed-wiring board. The nodes with high switching frequencies and
currents are short and are isolated from the noise-sensitive feedback circuitry. Careful attention has been
given to the routing of high-frequency current loops. See the data sheet for specific layout guidelines.
