Layout Guidelines

Proper board layout will help to ensure optimal performance

of the LM2770 circuit. The following guidelines are recom-

mended:

•

Place capacitors as close to the LM2770 as possible, and

preferably on the same side of the board as the IC.

•

Use short, wide traces to connect the external capacitors

to the LM2770 to minimize trace resistance and induc-

tance.

•

Use a low resistance connection between ground and the

GND pin of the LM2770. Using wide traces and/or mul-

tiple vias to connect GND to a ground plane on the board

is most advantageous.
