PCB Layout Considerations
Poor layout can degrade the performance of the DC-DC
converter and can be a contributory factor in EMI prob-
lems, ground bounce, thermal issues, and resistive voltage
losses. Poor regulation and instability can result.
The following design rules are recommended:
Place the inductor and filter capacitors as close to the
device as possible and use short wide traces between
the power components.
Route the output voltage feedback path away from
inductor and LX node to minimize noise and magnetic
interference.
Use a ground plane to further reduce noise interference
on sensitive circuit nodes.
