Application Information
(Continued)
Even under these peak power dissipation and ambient tem-
perature conditions, the junction temperature of the LM2788
is below the maximum operating rating of 125C.
As an additional note, the ambient temperature operating
rating range listed in the specifications is provided merely for
convenience. The LM2788 may be operated outside this
rating, so long as the junction temperature of the device
does not exceed the maximum operating rating of 125C.
Layout Guidelines
Proper board layout to accommodate the LM2788 circuit will
help to ensure optimal performance. The following guide-
lines are recommended:
Place capacitors as close to the LM2788 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 LM2788 to minimize trace resistance and induc-
tance.
Use a low resistance connection between ground and the
GND pin of the LM2788. Using wide traces and/or mul-
tiple 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 LM2788 typical application circuit, as pictured
on the cover of this datasheet
20044424

plane, assumed to be present, are located in the
center of the LM2788 footprint.)
