I am currently testing Conductive Immunity/Susceptibility (IEC 61000-4-6) on a product using the UCC28704 and the supply voltage collapses at levels 3(10Vrms) and level 2(3Vrms).
Once the field is removed the supply returns to normal. I suspect pin 6 (VS) is being affected. I have verified the UCC28704EVM also exhibits this problem. What do you recommend to solve this issue.
