Abstract: A control circuit for controlling a power module is provided. The power module drives a processing circuit. The control circuit includes a first resistor, a second resistor, a trigger circuit, and a switch circuit. The first resistor is coupled between a first reference voltage and a setting input terminal. The second resistor is coupled between a second reference voltage and the setting input terminal. The trigger circuit provides a switching signal in response to an operating signal. The switch circuit transmits a control signal to the setting input terminal in response to a first voltage level, and stops transmitting the control signal in response to a second voltage level. The power module executes one of a first power supply mode and a second power supply mode in response to a voltage value. When the control signal is not received, the power module executes a third power supply mode.

Abstract: A power supply circuit is adapted to an electronic device. The power supply circuit includes a drive circuit, a feedback resistor circuit, a battery module and a controller. The drive circuit receives a charger boost indication signal and generates a drive signal accordingly. The feedback resistor circuit has a feedback resistance value changing in response to the drive signal and receives a DC power supply to supply power to a system component. The battery module provides a battery power supply to the system component. The controller controls the battery power supply provided by the battery module according to the feedback resistance value. When the system component is operating in a heavy load state, the controller transmits the corresponding charger boost indication signal to the drive circuit, so as to reduce the feedback resistance value through the drive signal.
