EVM Assembly Drawings and Layout

Figure 5-1 through Figure 5-3 show the design of the TPS40077EVM-001 printed circuit board. The EVM has been designed using a double-sided, 2-oz copper-clad circuit board, with all components on the top side to allow the user to easily view, probe, and evaluate the TPS40077 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.
