Application Information

4.
Connect the ground pins of the LM3202, and filter ca-
pacitors together using generous component-side cop-
per fill as a pseudo-ground plane. Then connect this to
the ground-plane (if one is used) with several vias. This
reduces ground-plane noise by preventing the switching
currents from circulating through the ground plane. It
also reduces ground bounce at the LM3202 by giving it
a low-impedance ground connection.
Use wide traces between the power components and for
5.
power connections to the DC-DC converter circuit. This
reduces voltage errors caused by resistive losses across
the traces
Route noise sensitive traces, such as the voltage feed-
back path, away from noisy traces between the power
components. The voltage feedback trace must remain
close to the LM3202 circuit and should be routed directly
from FB to V
OUT
at the output capacitor and should be
routed opposite to noise components. This reduces EMI
radiated onto the DC-DC converter’s own voltage feed-
back trace.
