Abstract: A power supply is provided. The power supply includes a power supply circuit and a control circuit. The power supply circuit includes a voltage converter and multiple point-of-load circuits. The voltage converter generates a third voltage according to a first voltage. The load point-of-load circuits generate at least one second voltage and at least one state signal according to the third voltage. The at least one second voltage is suitable for supplying power to a load. The control circuit is coupled to the power supply circuit. The control circuit determines whether a single event latch-up occurs in the power supply circuit according to the at least one state signal. When the single event latch-up occurs in the power supply circuit, the control circuit switches off the power supply circuit to stop generating the at least one second voltage and the at least one state signal.
