EN/LZT 146 033 R1D Ericsson Power Modules, June 2004
PKB 4000 Datasheet
EMC Specication
The conducted EMI measurement was performed using a
module placed directly on the test bench.
The fundamental switching frequency is 160kHz for
PKB 4610 PINB @ 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.
The capacitors used are of ceramic type.
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 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
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.
