Page 18: 3.1 Layout
3.1 Layout Board layout is critical for all switch mode power supplies. Figures 1-5 show the board layout for the TPS65011EVM-049 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. -
