(Figure 10 through Figure 14 ) show the design of the TPS40180EVM printed circuit board. The EVM has
been designed using a four layer, 2-ounce, copper-clad circuit board with all components on the top side,
allowing the user to easily view, probe and evaluate the TPS40180 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.
