CHY103 working only in 5V mode

Posted by: alexandruc on

Hello,

We developed a board with the intention of delivering two Quick Charge 3.0 outputs from separate boost converters. The datasheet on CHY103 was not very comprehensive, but we assumed it would work the same with a boost converter as it does with the buck converter from the typical application schematic in the datasheet.

Does anybody know what the problem might be here? Every device that is plugged in is only being charged with the standard 5V output. I attached the schematic for reference.

Thank you,
Alex Chitic
