MP4560DN buck controller resetting Issue

Hello Team,

I am using part no MP4560DN-LF in my design. I set switching freq to 500Khz and build the circuit as per reference design provided in datasheet for 5V output.
But, when I power up the board buck controller on for 1 mS second only and shut down for 6 mS. Again it turn on for 1 mS and turns off for 6 mS. This keep repeating and hence I am not getting required output. It seems like buck converter is keep resetting continuously.


Please suggest probable cause and solution for it. Kindly see attached waveform at output of buck converter.

Hello namdev.panore,

Are you testing this on your own board or using the evb?

Hello Eduardo,

I am using my own board for testing this buck converter.

Hello namdev.panore,
Please share your schematic and layout.
