This DC/DC step-down voltage converter is based on MP2037, it converts input voltage between 4.5V and 23V into a smaller voltage between 1V and 17V, capable of driving a 1.8A load with excellent line and load regulation.

Note: Input must be >1.5V higher than output. High current output, the inductance will be hot.
