HI, I am using LM3481 as a SEPIC converter in on e of the product . I have used the 475KHz as switching frequency.
The product fails in the radiated emission test with peaks in the 300-350 MHz range. I have analysed on spectrum analyser with the help of near field probes and found out that the SEPIC inductors are raditaing so much noise around 300 MHZ .
can anybody help me out to resolve this issue?
