Abstract
A control chip providing power to a sink device and including a connection port, an encoder, a decoder, and a control circuit is provided. The connection port provides an output voltage and an inquiry signal to the sink device, and receives an acknowledgement signal provided by the sink device. The encoder generates the inquiry signal. The decoder decodes the acknowledgement signal to generate a decoded result. In a compensation mode, the control circuit obtains an actual voltage received by the sink device according to the decoded result and adjusts the output voltage according to the actual voltage received by the sink device. In a setting mode, the control circuit obtains a protect-point voltage of the sink device according to the decoded result and adjusts the output voltage according to the protect-point voltage of the sink device to prevent the output voltage from being higher than the protect-point voltage.
