8.4.2 Layout Example
Figure 8-15 Recommended
Layout for Single L-C FilterNote: For a single L-C configuration, the feedback
sense is placed near the VOUT capacitors. For a second L-C filter
design, the feedback sense is placed near the load after the
VOUT_FILT capacitors.
Figure 8-16 Recommended
Layout for Design with Second L-C FilterNote: The ferrite bead can be placed closer to the
device as long as it is placed > 8 mm from the device. This
placement avoids capacitive and electromagnetic coupling to the
output of the ferrite bead. If the ferrite bead is placed < 8 mm,
the filtering effect of the ferrite bead is greatly reduced. If the
ferrite bead is routed through a via to the back side of the board,
ensure adequate ground plane between the layers if the ferrite bead
is in this area.
