LAYOUT RECOMMENDATIONS
A good board layout of the LM2750 circuit is required to
achieve optimal assembly, electical, and thermal dissipation
perfromance.
Figure 4
is an example of a board layout
implementing recommended techniques. For more informa-
tion related to layout for the LLP package, refer to National
Semiconductor’s
Application Note 1187: Leadless Lead-
frame Package (LLP)
. Below are some general guidelines
for board layout:
Place capacitors as close to the as possible to the
LM2750, and on the same side of the board. V
IN
and
V
OUT
connections are most critical: run short traces from
the LM2750 pads directly to these capacitor pads.
Connect the ground pins of the LM2750 and the capaci-
tors to a good ground plane. The ground plane is essen-
tial for both electrical and thermal disspation perfor-
mance.
For optimal thermal performance, make the ground
plane(s) as large as possible. Connect the die-attach pad
(DAP) of the LM2750 to the ground plane(s) with wide
traces and/or multiple vias. Top-layer ground planes are
most effective in increasing the thermal dissipation capa-
bility of the LLP package. Large internal ground planes
are also very effective in keeping the die temperature of
the LM2750 within operating ratings.
