Tool/software:
Hi Experts
I am using the TPS5450DDAR step-down converter to obtain 3.3V from 12V. It powers a set of LEDs and the microcontroller on the PCB. Please see the schematic below. The issue is that radiated emission peaks are above the limit. Any suggestions for PCB modifications to improve this would be highly appreciated.
