Part Number:TPS1H100-Q1

Hi, Team:

We DIN TPS1H100-Q1 in Infotainment project but when run EMC test with no load but TPS1H100-Q1 enabled, we find there is a 10.2MHz RE spike close to TPS1H100-Q1. We checked, if disable the switch, the spike will disappear. 

Can you help to check and advise if  TPS1H100-Q1 will have internal 10.2MHz switching? If possible way to reduce it?
