EN/LZT 146 051 R7A Ericsson Power Modules, February 2007
PKM 4000E PI Datasheet
EMC Specification
The conducted EMI measurement was performed using a
module placed directly on the test bench .
The fundamental switching frequency is 180 kHz for
PKM4510E PI @ VI = 53V, IO = (0 .1 . . .1 .0) x IOmax .
External filter (class B)
Required external input filter in order to meet class B in
EN 55022, CISPR 22 and FCC part 15J .
Test set-up.
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 re-
turn switching noise to ground as directly as possible, with
improvements to both emissions and susceptibility. It is also
important to consider the stand-off of the PKM 4000E series
DC/DC converter. 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 con-
nected 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 capabil-
ity of routing the input noise and output noise back to their
respective returns .
