Hello friends, I am working on a project where I used flyback dc to dc converter to power up all circuit components.
My issue is related to switching frequency. When I use 100KHz switching frequency(using TOP Switch) my circuit works properly but when I switch to 400KHz (using DPA switch) the issue of noise interference in secondary side is started.
Is there any trend to use special filter capacitor/inductor at special locations to avoid primary sided noise from coupling with secondary sided circuit?
