Adjustable Step-Down Converter (1.0V–17V&1.8A): stable and efficient

This step-down converter, from Seeed Studio, is based on the MP2307 circuit. It converts input voltage between 4.5 and 23 Vdc into a smaller voltage between 1 and 17 Vdc, and is capable of driving a 1.8A load with peaks measured at 3A.

A few precautions for use

For the step-down converter to work correctly, the input voltage must always be 1.5V higher than the desired output. A current limit has been set internally in case the input is inferior to the desired output.
