A multi charging current control circuit including a voltage reference unit, a current limiting unit, a current detector and a current control unit is provided. The voltage reference unit provides many reference voltages. The current limiting unit selects a corresponding reference voltage from the reference voltages according to a charge mode signal and outputs a control signal according to the corresponding reference voltage. The current detector detects a first and a second charging current. The current control unit controls the first charging current and the second charging current according to the control signal. The current detector feedbacks the first charging current and the second charging current detected to the current control unit, such that the current control unit adjusts the first charging current or the second charging current to make the sum of the first charging current and the second charging current less than or equal to a constant value.

An apparatus for a power supply with brownout protection and the method thereof are proposed. As a brownout condition occurs, the apparatus informs at least one microprocessor to process the shutdown process timely. The apparatus includes a power factor correction (PFC) circuit, and a bus capacitor generating a bus voltage by receiving an input voltage via the PFC circuit, and a PWM circuit generating multiple output voltages for the microprocessor, and a supervisor circuit generating a power-good signal in response to a proportional bus voltage, and a brownout circuit for disabling the boosting operation of the PFC circuit under a brownout condition. When the boosting operation is disabled, the bus voltage starts to fall. As the proportional bus voltage is lower than a threshold voltage, the supervisor circuit generates the power-good signal. Therefore, the microprocessor can process the shutdown procedure timely.
