    • A switching power supply (96) receives an AC voltage and converts it to a regulated DC voltage. The switching power supply (96) includes a Vcc limiter (16) to limit the operating voltage at the power supply terminal (10) of a integrated regulator circuit (118). The Vcc limiter (16) limits the operating voltage at the power supply terminal (10). When operating voltage at power supply terminal (10) increases, a differential pair of transistors (22, 24) supply a differential current to a current mirror configuration of transistors (26, 30) to supply voltage to a drive transistor (36) to increase current in the drive transistor (36) to a value based on n times the current in a reference transistor (26). An increase in current through the drive transistor (36) counteracts increased operating voltage at the power supply terminal (10), thereby reducing the operating voltage level back to a desired level.
    • 开关电源(96)接收AC电压并将其转换成稳压的DC电压。 开关电源(96)包括用于限制集成调节器电路(118)的电源端子(10)处的工作电压的Vcc限制器(16)。 Vcc限制器(16)限制电源端子(10)处的工作电压。 当供电端子(10)上的工作电压增加时,差分对晶体管(22,24)将差分电流提供给晶体管(26,30)的电流镜面配置,以向驱动晶体管(36)提供电压以增加 驱动晶体管(36)中的电流为基于参考晶体管(26)中的电流的n倍的值。 通过驱动晶体管(36)的电流的增加抵消了电源端子(10)处的增加的工作电压,从而将工作电压电平降低到期望的水平。
