Material: Buck converter made of electronic components, internal conductor: pure copper.
Design: Step down module XL4015 can maintain a stable input voltage and limit the output current within a certain range. In addition to this function, Step down module also has a built in thermal shutdown function and output short protection function.
Note: The input voltage of the Buck converter should not exceed 38V, and the input voltage should be at least 1.5V higher than the output voltage. Pay attention to the USB port and do not apply a voltage exceeding 5V to the USB device.
