CPS2011S is a single-cell 8A high efficiency dual-phase switched capacitor charger. It integrated Universal Fast Charging Specification for Mobile Devices (UFCS PHY). It supports up to 12V input voltage, and operates in following 2 modes: Forward 2:1 (up to 8A IOUT) , Forward 1:1 (bypass, up to 5A IOUT). The switched capacitor architecture optimized for 50% duty cycle. The input Voltage is 2x of battery voltage and the output current is 2x of VBUS input current, which effectively reduces power loss across the input cable. CPS2011S integrates protection schemes including input/output over-voltage/current protection, and over temperature protection. It has built-in I2C slave interface for Application Processor configurations.
