CW6113 is a highly-integrated 3A switch-mode Li-Ion and Li-polymer battery charger with power path management. Its ultra-low impedance on power path helps improve charging efficiency, reduce charging time and extend battery life during discharge. The charging efficiency at 5V/3A is 93%. CW6113 supports USB-OTG with up to 1.5A supply current and 5.0V-5.5V output adjustable. Charging and system settings could be flexible configured via the I2C interface. Its compact FCQFN 4x4mm package, combing with using 0.68uH small profile inductor, makes it a good selection for fast charging application.
