The Buck 13 Click Board™ is a high-efficiency step-down converter that provides a highly regulated output voltage derived from the connected power source, rated from 4.5V to 5.5V. The regulated output voltage is 3.3V, the most common choice for various embedded applications. The Buck 13 Click Board™ is based around an integrated DC-DC converter, labelled as MPM3530.
Due to its high efficiency, MPM3530 allows the Click Board™ to easily deliver up to 3A of current. The MPM3530 is very reliable, offering over-current and over-voltage protection, as well as a thermal shutdown.
