Which power converter topology can be best suited for EMC compliance for small power converter to be used in LED lighting products. In my context I'm using a 5W non-isolated AC-DC converter which is not complying as per EN-55015 standard. Any suggestion to use isolated Flpyback topology for the same application if this can yield better EMI performance ove non-isolated buck.
