Board Layout
This section provides the TPS650380EVM-054 board layout and illustrations.
Board layout is critical for all high-frequency, switch-mode power supplies.
through
show the board layout for the TPS650380EVM-054 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. Also, the
majority of the heatsinking for this device occurs through the top layer traces and vias pulled from the IC's
solder bumps that carry high currents. See the data sheet for specific layout guidelines.
