Layout Recommendation
The radiated EMI performance of the DC/DC converter will be
optimised by including a ground plane in the PCB area under
the DC/DC converter. This approach will return switching
noise to ground as directly as possible, with improvements to
both emissions and susceptibility. If one ground trace is used,
it should be connected to the input return. Alternatively, two
ground traces may be used, with the trace under the input side
of the DC/DC converter connected to the input return and the
trace under the output side of the DC/DC converter connected
to the output return. Make sure to use appropriate safety isola-
tion spacing between these two return traces. The use of two
traces as described will provide the capability of routing the
input noise and output noise back to their respective returns.
