Hi There,

We used this chip in our 12-5 voltage converter, I want to get out of each channel 15A for a total of 30A max at 3.8v. the issue I have is that channel 1 is limiting at 6.4A.  

I am not sure what is causing this since they both have the same COMP input.

Web browser did not let me attached the PDF, could you please give me an email where I can send it to?

Regards,

Mario Bejarano
