PKJ 4216N PIT Datasheet
EMC Specication
The conducted EMI measurement was performed using a
module placed directly on the test bench.
The fundamental switching frequency is 210 kHz for
PKJ 4216N PIT @ VI = 53V, IO = (0.1...1.0) x IOmax.
External lter (class B)
Required external input lter in order to meet class B in
EN 55022, CISPR 22 and FCC part 15J.

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 switch-
ing noise to ground as directly as possible, with improve-
ments to both emissions and susceptibility. It is also impor-
tant to consider the stand-off of the PKJ 4216N PIT DC/DC
converter. If one ground trace is used, it should be connect-
ed 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 isolation
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.
