  • WIRELESS CHARGING OF AN ELECTRONIC DEVICE
    Publication number: 20230387724
    Abstract: A method for wirelessly charging an electronic device includes entering, by a first electronic device a wireless charging mode upon determining that a second electronic device is accessing the first electronic device; the first electronic device setting a power transmission duty ratio of the first electronic device at a first level; the first electronic device wirelessly supplying power to the second electronic device at the power transmission duty ratio; the first electronic device monitoring a current value of the first electric device used to provide the power to the second electronic device; and the first electronic device controlling the power transmission duty ratio according to the monitored current value.

  • DC-DC converting circuit and a power management chip package including the same
    Patent number: 9939828
    Abstract: A direct current (DC)-DC converting circuit includes a voltage converter generating a regulation current in response to a driving signal and generating an output voltage and an output current; an output voltage regulator regulating the output voltage and outputting a first control signal; a voltage limiter limiting a voltage value of the first control signal below a threshold value; a current sensor sensing an intensity of the regulation current and generating a second control signal having a voltage value corresponding to a value of the sensed intensity; and a driving signal generator generating the driving signal based on the first and second control signals, the first control signal having the voltage value below the threshold value.
