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.
