Board Layout
This section provides the TPS65560EVM-165 board layout and illustrations.
3.1
Layout
Board layout is critical for all high-frequency switch mode power supplies.
the board layout for the TPS65560EVM-165 PCB. 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 and a single-point grounding scheme is used for all high-current and
high-voltage traces. See the data sheet for specific layout guidelines.
