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.
