6 TPS62690/1/2/3EVM Assembly Drawing and Layout

Figure 10 through Figure 14 show the design of the TPS62690/1/2/3EVM-076 printed-circuit boards

(PCB). 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 show how the board is laid out; they are not

intended to be used for manufacturing TPS62690/1/2/3EVM-076 PCBs. Note the connection

of the TPS6269x feedback (FB) pin. It is recommended that the FB pin be connected directly

to the inductor, not directly on the VOUT connection of the output capacitor. The connection

to the inductor provides better transient response performance.
