3.1 Layout
Board layout is critical for all switch mode power supplies. Figures 3–1, 3–2,
and 3–3 show the board layout for the TPS61042EVM–226 PWB. The nodes
with a high switching frequency are short and are isolated from the noise sensi-
tive feedback circuitry. Careful attention has been given to the routing of high
frequency current loops. Refer to the data sheet for specific layout guidelines.
