Abstract
A mobile device charging system includes a mobile charger and a mobile device. The mobile charger includes: an adaptive power converter for receiving data signals and generating a DC signal; an output terminal; and a charging cable for transmitting the data signals and receiving the DC signal to provide an output signal at the output terminal. The mobile device includes: a device-side connector for receiving power transmitted from the output terminal; and a charging control circuit for generating and transmitting the data signals to the adaptive power converter through the device-side connector and the charging cable. The adaptive power converter adjusts the magnitude of the DC signal according to the data signals to control the voltage drop of the charging cable to be less than a predetermined threshold.
