Hi PAN-M,

Clarify the question, you want to use LMZ31707 directly replace LMZ31710 without any external circuit change, right?

Thanks,

Lishuang

Yes, our customer wants to be usable with both devices because thinks availability.

The difference is primarily in the current limit options available in the devices. With the different current limit options, there is also a slight change in the gmps which affects the loop gain.
