This is a switching DC/DC converter which operates at a 5 MHz frequency. It is not possible to eliminate this frequency entirely.
You can add a ferrite bead on the input and/or output to block this frequency from other circuits. What issue is this frequency causing in your system?
We also have the TPS8268120 in the same size package.
Thank you for sharing your data.
What is the x-axis and its units? I don't see 5 MHz on the graph.
As well, there are peaks that are higher than the area in the red box. Is it just the frequency range that is important to stay out of?
Where and how was that measured? Is it the actual signal or its radiation that is measured?
What is the load current?
