The following figures (Figure 12 through Figure 16 ) show the design of the TPS40131EVM 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 TPS40131 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.
