EVM Assembly Drawings and Layout
The following figures (
through
) show the design of the TPS53129EVM-621
printed-circuit board (PCB). The EVM has been designed using a 4-layer, 2-oz copper-clad circuit board of
3.5 inch by 2.7 inch to allow the user to easily view, probe, and evaluate the TPS53129 control integrated
circuit 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.
