TPS826xxEVM Assembly Drawings and Layout

Figure 5 through Figure 7 show the design of the show the design of the TPS826xxEVM-646 printed

circuit boards. The EVM has been designed using a two-layer, 1-ounce copper-clad PCB with all

components in an active area on the top side of the board. Moving components to both sides of the PCB

or using additional internal layers can offer additional size reduction for space-constrained systems.

NOTE:

Board layouts are not to scale. These figures are intended to show how the board is laid out;

they are not intended to be used for manufacturing TPS826xxEVM-646 PCBs.

Note the connection of the TPS8267x feedback (FB) pin. It is recommended to connect the

FB pin directly to the inductor, not directly on the V

connection to the inductor is recommended because it provides better transient response

performance.
