This DC-to-DC buck converter reduces the voltage it receives from 6V to 32V to a lower output voltage, typically 5V. It can also automatically adjust the output voltage between 3V and 12V when fast charging is activated. As a result, it can provide up to 24W of power (for example, 5V at 3.4A, 9V at 2.5A, or 12V at 2A), depending on the input and output voltage settings. Additionally, this module has several protective features, such as protection against high or low input voltage, over-current issues, short circuits, and overheating. These features make it suitable for a wide range of applications. Compared to the popular three-terminal linear regulators, this module operates more efficiently as a switch-mode power supply, especially when dealing with higher input voltages.
