show the design of the TPS40130EVM-001 printed circuit board. The EVM has
been designed using a 4-layer, 2-oz copper-clad circuit board 4.5"
×
4.0” with all components on the top
side to allow the user to easily view, probe, and evaluate the TPS40130 control IC in a practical
application. Moving components to both sides of the PCB or using additional internal layers can offer
additional size reduction for space constrained systems.
