Board Layout

3.1Layout

Board layout is critical for all switch mode power supplies. Figure 1 through Figure 5 show the board layout for the TPS65020EVM-110 PWB. 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 to the datasheet for specific layout guidelines.
