SGM66099 Synchronous Step-Up Converter with Ultra Low Quiescent Current GENERAL DESCRIPTION The SGM66099 is a synchronous step-up converter with 0.65μA ultra low quiescent current. It is designed for products powered by alkaline battery, NiMH rechargeable battery, Li-Mn battery or rechargeable Li-Ion battery, for which high efficiency under light load condition is critical to achieve long battery life operation. The SGM66099 step-up converter only consumes 0.65μA quiescent current under light load condition and can achieve up to 75% efficiency at 10μA load with fixed output voltage version. It can also support up to 300mA output current from 3.3V to 5V conversion, and achieve up to 93% efficiency at 200mA load.
