8.4.2 Layout Example

GUID-20220907-SS0I-CVRG-TVN0-N1BJR8NTWJH8-low.gif Figure 8-15 Recommended Layout for Single L-C Filter
Note: 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.
GUID-20220907-SS0I-NMB7-CBGQ-D9NWTF8F3HGF-low.gif Figure 8-16 Recommended Layout for Design with Second L-C Filter
Note: 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.
