MT3608 DC-DC converters in parallel with common output
Has anyone experience with these converters?, Any advice?


The MT3608 that naturally produces a few milli volts (or several tens of mV) greater output voltage compared to the other one will win the "diode battle" and supply circa 90% of the load current.

But it gets a little worse. The diode supplying most of the load current will warm up more than the other and its forward voltage will drop hence, the "circa 90%" figure might become circa 95%: -



Picture from here.

Is this what you want?

By the way, you drew you circuit incorrectly. It should be like this: -
