3 Board Layout
This section provides the TPS6116xEVM-243 board layout and illustrations.
Board layout is critical for all high-frequency, switch-mode power supplies. Figure 4 through Figure 4 show
the board layout for the TPS6116xEVM-243 printed circuit board (PCB). The nodes with high-switching
frequencies and currents are kept as short as possible to minimize trace inductance. Careful attention
Was given to the routing of high-frequency current loops: a single-point grounding scheme is used. See
the data sheet for specific layout guidelines.
