Layout Guidelines
Proper board layout to accommodate the LM2797/98 circuit
will help to ensure optimal performance. The following guide-
lines are recommended:
Place capacitors as close to the LM2797/98 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 LM2797/98 to minimize trace resistance and induc-
tance.
Use a low resistance connection between ground and the
GND pin of the LM2797/98. Using wide traces and/or
multiple vias to connect GND to a ground plane on the
board is most advantageous.
Figure 2 is a sample single-layer board layout that accom-
modates the LM2797/98 typical application circuit, as pic-
tured on the cover of this datasheet
20044524
