This DC/DC step-down voltage converter's input voltage between 4.5V and 28V into a smaller voltage between 0.8V and 18V, capable of driving a 3A load with excellent line and load regulation.

Note: Input must be >1.5V higher than output! The chip will get to high temperature protection mode when it work at a high-power conversion, without any cooling, it is able to output 3A current at 5V. But at higher output voltage, the current output capacity is lower than 3A, approx 2A.
