Step-down converter with adjustable current and voltage

Connection, temperature test and an example of using as a LED driver and for charging batteries, down-converter with current and voltage regulation. The converter is assembled on the XL4015E1 microcircuit. There are 3 LEDs on the board for indication: the first is on when there is no load, the second when there is a load, the third when current limiting is active. To adjust the current and voltage, there are 2 potentiometers of 10 kΩ on the module.
According to the specification, the input voltage should be in the range from 5 to 32 volts. The output voltage is adjustable from 0.8 to 32 volts. The second potentiometer regulates the maximum current from 0 to 5 amperes.
This down converter can be used as a LED driver or charging for lithium-ion and other batteries. In addition, on the basis of such a module, you can make a laboratory power supply.
