5 Board Layout
This section provides the board layout of the TPS63030EVM-658. A 2-layer PCB with a number of vias
near the LED was used to help with the thermal dissipation of the WLED. Users must carefully design
their system to handle the thermal challenges raised by the WLEDs.
Board layout is critical for all switch-mode power supplies. See the data sheet (SLVS893) for specific
layout and routing guidelines.
