7 TPS53114EVM-541 Assembly Drawings and Layout
The following figures (Figure 8 through Figure 12) show the design of the TPS53114EVM-541 printed-
circuit board (PCB). The EVM has been designed using a 4-layer, 2-oz, copper-clad circuit board 48 cm x
93 cm with all components on the top side to easily view, probe, and evaluate the TPS53114 control
integrated circuit in a practical 4-layer application. Moving components to both sides of the PCB or using
additional internal layers can offer additional size reduction for space constrained systems.
