The Buck 12 Click Board™ is a high-efficiency step-down converter that provides 3.3V on its output, derived from the connected power supply voltage, in the range from 4.2V to 18V. Buck 12 Click Board™ is based on the MPQ8632, a highly efficient DC-DC step-down converter. In addition, the Buck 12 Click Board™ offers to monitor the input and output voltage stability by employing an additional A/D converter circuit. Due to its high efficiency, MPQ8632 allows the Click Board™ to efficiently deliver up to 4A of current. It features a package that enables a low noise performance, high efficiency, and very compact size while maintaining compatibility with higher current ICs from the family.
