TPS92611-Q1: TPS92611 Tail light BCI Test Question

Part Number: TPS92611-Q1

Hello Frank,

Customer BIC test TIS62611 test Fail (350MHz-400MHz @CI: 200mA test band found LED light/dark flashing)
The schematic is below, Layout source I will Email it to you, please help if there are suggestions to improve the countermeasures?

Product specifications:
VIN: 10~16V
Out: 9V/180mA

BCI test conditions (customer factory specifications 200MHz ~ 400MHz is more stringent)


 
In addition, the customer has found that if the input voltage of the TPS92611 is raised from the low voltage to the VF point of the LED, the LED will flash. This application for the customer is approximately 9.2V.Is this a normal action?

The customer feels that this may be caused by this reason.

Best Regards,

Kami Huang
