CPS2011 is a single-cell 7A high efficiency dualphase 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 7A 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.
