Layout
The board layout for the TPS54980EVM022 is shown in Figure 31 through
Figure 36. The topside layer of the TPS54980EVM022 is laid out in a
manner typical of a user application. The top and bottom layers are 1.5-oz.
copper, while the two internal ground plane layers are 1-oz. copper.
The top layer contains the main power traces for V
I
, V
O
, and V
phase
. Also on
the top layer are connections for the remaining pins of the TPS54980 and a
large area filled with ground. The bottom layer contains ground and some
signal routing. The top and bottom ground traces are connected with multiple
vias placed around the board including 12 directly under the TPS54980 device
to provide a thermal path from the PowerPAD
land to ground.
The input decoupling capacitors (C5, C9, and C19), bias decoupling capacitor
(C4), and bootstrap capacitor (C3) are all located as close to the IC as
possible. In addition, the compensation components are also kept close to the
IC. The compensation circuit ties to the output voltage at the point of
regulation, adjacent to the high frequency bypass output capacitor.
