EVM Assembly Drawings and Layout

Figure 6-1 through Figure 6-6 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.
