Classification: CPC H  Y | IPC H

Claim 0:
1. A power supply, comprising:
a power supply circuit generating at least one second voltage and at least one state signal according to a first voltage, wherein the at least one second voltage is suitable for supplying power to a load; and
a control circuit coupled to the power supply circuit, wherein the control circuit determines whether a single event latch-up occurs in the power supply circuit according to the at least one state signal, and 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,
wherein the power supply circuit comprises:
a voltage converter generating a third voltage according to the first voltage; and
a plurality of point-of-load circuits coupled to the voltage converter, wherein the plurality of point-of-load circuits generate the at least one second voltage and the at least one state signal according to the third voltages,
wherein the control circuit receives a fourth voltage, the fourth voltage is a periodic voltage, and when the single event latch-up occurs in the power supply circuit, and the fourth voltage is switched from a first voltage level to a second voltage level, the control circuit switches on the power supply circuit.
