We have been using MP2452 in one of our products. During the Conducted Emission test, we have been getting noise signals at 1 MHz frequency. The MP2452 is working at 1 MHz. Also, we have identified with various tests that the noise is generated due to this chipset only.

Can you please help us how can we remove this noise?

Hello @parth,

Welcome to MPS forums. In order to investigate on the root cause of the noise, can you share your schematic and layout?
