Board Layout
Board Layout, Schematic, and Bill of Materials
This section provides the TPS780xxxEVM-301 board layout, schematic, and bill of materials.
Board layout is critical for all high-frequency switch mode power supplies. If the layout is not carefully
done, the regulator could show stability problems as well as EMI problems. Therefore, use wide and short
traces for the main current path and for the power ground tracks. The input and output capacitor, plus the
inductor should be placed as close as possible to the IC. Use a common ground node for power ground to
minimize the effects of ground noise.
