Question
Do I need to follow the recommendations of AN-0971 to achieve EMI emissions
targets?
Answer
The ADuM5x1x and ADuM6x1x parts offer less of an EMI challenge than previous
isoPower devices. The main reason for this is that the new parts are targeted
at lower total power, so the peak currents in the tank oscillator are lower. At
very low load, (
level, you should read and follow the recommendations in AN-0971, however
reduced levels of stitching capacitance are required to achieve the same EMI
goals.
