The Buck 14 Click Board™ is based around the BMR4613001/001, a PoL regulator from Flex. It's a high-efficiency step-down converter that provides a highly regulated output voltage derived from the connected power source, rated from 4.5 to 14V. The regulated output voltage can be selected between 0.6V and 5V.
The Buck 14 Click Board™, due to the high efficiency of BMR4613001/001 allows the Click Board™ to easily deliver up to 12A of current with a maximum of 60W of power and high efficiency, typically 96 % at 12Vin, 5Vout and 80% load.
