Radio Circuit. - This is one of implementation of XL4015 IC to build adjustable power supply system. It is only need small component completed to build this electronic circuit that basically component.
The electronic design circuit of adjustable power supply using XL4015 IC is look like in Figure 1 below. Other component used like resistors, capacitors, transistor, inductor, etc.

Description
The electronic circuit design like in Figure 1 above show you adjustable power supply using XL4015 IC. Other component need also that can supply with low voltage DC +4 - 36V and ground source to charge this IC and all system component from power supply built. With this electronic design circuit you can produce touch on/off switch that useful now.
According Electroschematics blog mentioned that power up the module with a stable and accurate dc power supply (such as a regulated 6-V power supply). Then short-press the button on the right side to select which one you need to adjust (input or output). Long-pressing the button on the right side (holding it for >2 s) makes the module enter calibration mode. After releasing the button, the related LED will blink to indicate which voltage is now calibrating, and the numeric display will blink with the present value.
Short-press the button to change the present value. For example, if your power supply is 6 V but the result of voltage meter is 5.8 V, you need to set the value to 6 V. Short-press the button on the right side to increase the voltage by one unit. Short-press the button on the left side to reduce the voltage by one unit.
Long-press button on the right side to store the redressed value. The preset pot sets the actual output voltage. Calibrate the output voltage reading on the digital voltmeter in the same way above. For example, if your actual output is 3 V but the result on the voltmeter is 4 V, you need to set the value to 3 V. The redressed value will be stored in the non-volatile memory of the module.
