I notice some issue with handy XL4015 Step-Down DC Module with CV/CC Control, so I ask if that can be fix or lower/minimise effect...
Its about that module cant hold CC when voltage is set less than 1.7v
If you have that module, please confirm that.
Here is visualisation table for fixed 100mA CC, measuring output in short :
set 3.0v - 100mA/0.00v in short
set 2.0v - 100mA/0.00v in short
set 1.8v - 100mA/0.00v in short
set 1.7v - 100mA/0.00v in short
set 1.6v - 300mA/0.00v in short
set 1.5v - 900mA/0.00v in short
set 1.4v - 1.8A/0.45v in short
In schematic pin #2 is going to voltage set trimpot, and near TL431 trimpot is for set current.
I'll be glad if I can modified it for more reliable use, but dont know how, it will be awesome if it can work with low voltage and correctly hold current.
