6 EVM Assembly Drawings and Layout
Figure 6-1 through Figure 6-6 show the designs of the TPS54291EVM-431 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 in a
0.86-inch × 1.28-inch active area on the top side and all active traces to the top and bottom layers to allow the
user to easily view, probe, and evaluate the TPS54291 control IC in a practical double-sided application. Moving
components to both sides of the PCB or using additional internal layers can offer additional size reduction for
space constrained systems.
