CPS2021 is a single-cell 7A high efficiency dualphase switched capacitor charger. It integrated fast charging protocol (SCP PHY) and 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.
