SY5111
The SY5111 is a high efficiency step down converter with ultra low quiescent current of typical 200nA. The device is typically paired with a 2.2µH inductor and a 10µF output capacitor,
providing a typical output current of 300mA. The device uses COT technology with a typical switching frequency of 1.2MHz. In power save mode, the light load efficiency can be
extended down to 100μA load current, and the efficiency can reach 90%. After start-up, the device operates at an input voltage as low as 2.15V, so it can be powered directly by a single Li-MnO2 button battery.
