Hi Kinetek,

To correctly find that part number for you, could you please provide the Input and Output voltage of the device?

For your reference, here is MPS Packaging information.

This is a step down converter. Input is from 5VDC to 20VDC probably. Output do not know for sure 3.3V and 2.5V.

Thanks

But, I still need the correct ordering code, please.

Hello Kinetek,

I believe the part is NB687. Please find the DS of the part here

NB687(28V, Low IQ, High-Current,Synchronous Buck Converterwith Integrated VPP/VTT/VTTREF)

This is cip with tip marking AVT as it states on pdf. Mine is BJE. Are you sure that those are the same units?
