The Buck 8 Click Board™ is a high efficiency, wide voltage range, and high current synchronous step down (buck) DC-DC converter, featuring two enhanced modes that can be used to drive lighter loads with increased efficiency. The output voltage can be adjusted by the multi-turn trimmer potentiometer.
Since the output voltage is set mechanically, it will retain the set value, even after the restart. Very high-efficiency results with the reduced power dissipation, thus allowing reasonably high power to be delivered to the load, connected to the output terminal. Internal feedback compensation across the whole voltage range allows a lower number of external components.
