This section provides the TPS62560EVM-330 board layout and illustrations.
Board layout is critical for all high-frequency switch mode power supplies. Figure 5 through Figure 7 show
the board layout for the TPS62560EVM-330 printed-circuit board. The nodes with high switching
frequencies and currents are kept as short as possible to minimize trace inductance. Careful attention has
been given to the routing of high-frequency current loops. A single-point grounding scheme is used. See
the TPS62560 data sheet for specific layout guidelines.
