Recommend converters for 5V line 20A?

Question

Electronics

Hello.
Please recommend converters like max8686, with which you had experience in creating a 5V line, so that there would be automatic adjustment of the output voltages and that the converters would be scaled. Approximately 20A. Now it’s max8686, it outputs stably 12A, when the load rises above 14A, the voltage starts to drop, there is a desire to install another one that would work in pairs (since it is compact and the device is small-sized), but at a price of 12 euros apiece, it’s strong with such don't roam. I need something similar but cheaper.

Yuzali IR3847, though under 3.3V. I gave 15A without any problems right according to the scheme from the datasheet.
