摘要：A power supply circuit coupled to a power source for providing electronicenergy to a workload includes a first switch, a control circuit, a first diode, and a backuppower, in which the input of the first switch is coupled to the power source, the output of
the first switch is coupled to the workload. the control circuit is coupled to the controlterminal of the first switch for determining the state of the power source, the anode ofthe first diode is coupled to the power source, the cathode of the first diode is coupledto the first terminal of the backup power, the first terminal of the backup power isfurther coupled to the workload, when the control circuit determines that the powersource is in a power-off state, a control signal is applied to the control terminal of thefirst switch to turn off the first switch.
