    • An apparatus and method for controlling a supply voltage of a multiple interface card includes a first voltage adjustment unit, a second voltage adjustment unit, an internal circuit, a first voltage controller, and a second voltage controller. The first voltage controller adjusts a first supply voltage to a first internal supply voltage used as an operating voltage of the internal circuit and supplies the first internal supply voltage to the internal circuit. The second voltage adjustment unit adjusts a second supply voltage to a second internal supply voltage used as an operating voltage of the internal circuit and supplies the second internal supply voltage to the internal circuit. The first voltage controller detects the first supply voltage and, according to the first supply voltage, either applies the first supply voltage to the first voltage adjustment unit or blocks the first supply voltage from the first voltage adjustment unit. The second voltage controller detects the second supply voltage and, according to the detected voltage, either applies the second supply voltage to the second voltage adjustment unit or blocks the second supply voltage from the second voltage adjustment unit.
    • 用于控制多接口卡的电源电压的装置和方法包括第一电压调节单元,第二电压调节单元,内部电路,第一电压控制器和第二电压控制器。 第一电压控制器将第一电源电压调整到用作内部电路的工作电压的第一内部电源电压,并将第一内部电源电压提供给内部电路。 第二电压调整单元将第二电源电压调整为用作内部电路的工作电压的第二内部电源电压,并将第二内部电源电压提供给内部电路。 第一电压控制器检测第一电源电压,并且根据第一电源电压将第一电源电压施加到第一电压调节单元,或者阻止来自第一电压调节单元的第一电源电压。 第二电压控制器检测第二电源电压,并且根据检测到的电压,将第二电源电压施加到第二电压调节单元,或者阻止来自第二电压调节单元的第二电源电压。
