EMC Specification
The conducted EMI measurement was performed using a
regulator placed directly on the test bench. The fundamental
switching frequency for PMB 8000 is 300 kHz. The measure-
ment below has been performed with Vin = 12 V, Vout = 5 V
and max load. Input filter 4 x 4.7 mF and output filter 2 x 150
mF was used during the measurement.

Layout Recommendation
The radiated EMI performance of the DC/DC regulator will
be optimised by including a ground plane in the PCB area
under the DC/DC regulator. This approach will return switch-
ing noise to ground as directly as possible, with improve-
ments to both emissions and susceptibility.
