PMB8510P

DC/DC regulator Input 8.3 - 16 V Output 16 A

Ericsson  

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.
