The total space required for the IC and the capacitors on the EVM is only about
10 mm × 12 mm = 120 mm
2
. The capacitors are not optimized for space. They
are optimized for performance. It is possible to use smaller capacitors to
optimize the layout for minimum board space. On the EVM, it is also possible
to solder some other capacitors because 1206-size pads have ben added in
parallel to C
IN
and C
OUT
.
The signal on the bottom is the ground signal (GND). For good performance,
the entire bottom layer is one GND plane, only interrupted by some vias.
Figure 2–3 and Figure 2–4 show the layout of the board.
