EVM Assembly Drawings and Layout

Figure 4

through

Figure 9

show the design of the TPS65070EVM-430 printed circuit boards. This EVM

has been designed using a four-layer, 1-ounce copper-clad PCB with all components in an active area on
the top side of the board.

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 TPS65070EVM-430 PCBs.
