Abstract: A power transmission chip is coupled between an external converter circuit and a controller chip and includes a first transmitting interface, an internal converter circuit, a second transmitting interface, and a processing circuit. The first transmitting interface is coupled to the external converter circuit to receive a conversion voltage. The internal converter circuit processes the conversion voltage to generate an analog signal. The second transmitting interface transmits the analog signal to the controller chip and receives a control command from the controller chip. The processing circuit generates an adjustment signal based on the control command and provides the first adjustment signal to the external converter circuit via the first transmitting interface. The external converter circuit adjusts the conversion voltage based on the adjustment signal.

Abstract: A dynamic protection circuit including an adjustment circuit, a detection circuit, a control circuit, and a counter circuit is provided. The adjustment circuit adjusts an output voltage based on a predetermined value. The detection circuit detects whether the output voltage is higher than an upper-limit value or lower than a lower-limit value. The control circuit changes the predetermined value and disables the detection circuit while the predetermined value is being changed. The counter circuit starts to adjust a count value in response to the detection circuit being disabled. In response to the counter circuit adjusting the count value, the control circuit adjusts the upper-limit value and the lower-limit value to be proportional to the output voltage. In response to the count value being equal to a target value, the counter circuit enables the detection circuit.

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.

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.
