Test set-up
Layout recommendation
The radiated EMI performance of the DC/DC converter will
depend on the PCB layout and ground layer design.
It is also important to consider the stand-off of the DC/DC
converter. With regards to the isolation requirements avoid
placing a conductor which is connected to the primary side
below the DC/DC converter.
If a ground layer is used, it should be connected to the output
of the DC/DC converter and the equipment ground or chassis.
A ground layer will increase the stray capacitance in the PCB
and improve the high frequency EMC performance.
Output ripple and noise
Output ripple and noise measured according to figure below.
See Design Note 022 for detailed information.
