Board Layout
Figure 6. Voltage-Mode Load Transient
This section provides the TPS61054EVM-350 board layout and illustrations.
Board layout is critical for all high-frequency, switch-mode power supplies.

show the board layout for the TPS61054EVM-350 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. See the device
data sheet (
