XL4015 Adjustable Step-Down Board Buck Converter DC-DC Regulator Module

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 1.5 V higher than the output voltage. Pay attention to the USB port and do not apply a voltage exceeding 5 V to the USB device

This product is a 180 KHz fixed frequency PWM buck (step-down) DC/DC module, capable of driving a 5A load with high efficiency, low ripple and excellent line and load regulation.The module with a voltage meter to display the input voltage and output voltage, and the voltage can be corrected through the button to improve the accuracy of the voltmeter.

Features:
- LED power indicator.
- Button to switch measurement of the input or output voltage, and an LED indicates the current measurement of the input or output voltage; The nixie tube can be turned off by another button. The mentioned states can be memorized, and are not lost even if the power is disconnected. (On-board marked "IN" LED is turned on, the nixie tube displays the input voltage value, "OUT" LED bright display is the output voltage value).
- Special launch, the voltmeter calibration function, will never exist voltmeter inaccurate!
