OPTIMIZINGLAYOUT
Optimizing a PC board layout involves to observe
the following rules which in generalcan avoid ap-
plication problems associated with ground loops
and anomalous recirculation currents. The elec-
trolytic capacitor for the power supply must be
kept as close to the IC as possible. It is important
that power grounds are close to each other on a
wide enough. Copper side also, it is important to
separate on the board the logic ground and the
power ground in such a way that the ground
traces for the logic signals and references do not
cross the ground traces for the power signals.
Logic ground and power ground must meet at
one point on the board (startpoint grounding) far
enough away from where the power ground
traces terminate to ground (sense resistors and
recirculation diodes). This is to avoid anomalous
interface with the logic signals. It is generally a
good idea to connect a non inductive capacitor
(typically 100nF) between the pins VS and GND.
In other cases it may be necessary to also place
a by-pass capacitor between the pins Vref and
GND.
