UCC33xx0-Q1 family passes CISPR25 Class 5 due to proper EMI filter selection and PCB layout. CE is passing due to the use of a tightly coupled connection using a "T-shape" cable and the selection of a HF pi filter with a dual DM inductor. RE is passing due to the use of the FB in the EMI filter and PCB layout techniques like Faraday shield, use of ground planes, KOZ and copper cut underneath the DM inductors and FB.
