Printed Circuit Board (PCB) Layout
3 Printed Circuit Board (PCB) Layout
PCB layout is critical for all switch-mode power supplies. Figure 2, Figure 3, and Figure 4 show the board layout for the TPS60230EVM-047 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. Refer to the product datasheet (SLVS516) for specific layout guidelines.
