show the design of the TPS40075EVM-001 printed circuit board. The EVM has

been designed using a 4-layer, 2-oz. copper-clad circuit board 3.0 inch × 3.0 inch with all components on
the top side to allow the user to easily view, probe, and evaluate the TPS40075 control device 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.
