PENGLIN 5PCS DC Buck Converter Voltage Regulator, MINI560 7 20V to 5V 5A Step Down Power Module for Transformer

This module can be used in the field of voltage reduction where the input voltage is higher than the output voltage, such as batteries, DIY mobile power supplies, communication equipment power supplies, power transformers, DIY adjustable voltage regulators, vehicle-mounted notebook power supplies, industrial equipment voltage reduction, etc. DC-DC buck converters utilize an integrally formed power inductor and synchronous control chip, resulting in a smaller and more efficient design. This integrated approach helps to improve the overall performance of the converter by reducing size, increasing efficiency, and enhancing power capabilities. By combining the power inductor and control chip, DC-DC buck converters can achieve higher levels of efficiency and reliability in various applications. Find the adjustable potentiometer, then using a screw driver to adjust a potentiometer. It can be minute adjustments to achieve a precise voltage. Do not exceed the rated voltage of the input voltage. Do not overload the output.
