10 EVM Assembly Drawings and PCB Layout

The following figures (Figure 10-1 through Figure 10-6) show the design of the TPS56121EVM-601 printed circuit board. The EVM has been designed using a 4-layer, 2-oz copper-clad circuit board 2.5” x 2.5” with components on both sides of the PCB to allow the user to view, probe and evaluate the TPS56121 high current converter with integrated FETs in a small form factor, high-current application.
