Abstract
An adaptive buck converter of a charging cable includes: a power receiving interface for receiving a DC voltage and a cable current from a cable; a terminal communication interface for transmitting a charging voltage and a charging current to a connection terminal of the charging cable and for receiving a communication signal generated by a mobile device from the connection terminal; a power converting circuit for receiving the DC voltage and the cable current from the power receiving interface and for generating the charging voltage and the charging current; a monitor circuit arranged to operably detect the DC voltage or the cable current; and a data processing circuit configured for controlling the power converting circuit according to the communication signal. The data processing circuit further communicates with the mobile device through the terminal communication interface and the connection terminal in response to a detection result of the monitor circuit.
