R1801K Power-Storing Buck DC-DC Converter

Nisshinbo R1801K Power-Storing Buck DC-DC Converters are optimized for photovoltaic energy harvesting applications. The R1801K offers an ultra-low 200nA quiescent current (IQ), a high 80% efficiency at 10μA, and a minimum starting power of 1.00μW (VIN=4.0V, VOUT=3.0V). This device also features a Maximum Power Point Control (MPPC) function and a reverse current protection function. The former function optimizes the efficiency of power supply from a photovoltaic element, and the latter cuts off the reverse-current path when power is off to prevent power loss caused by reverse current.
