Output monitoring circuit activated if a preset voltage level is exceeded. Depending on the type of circuit used, the OVP shuts the converter down, "crowbars" the faulty output or switches the converter to a different operating mode.
The use of circuitry which will protect the user's system in the event of a failure in the power supply. This circuit will limit the output voltage to a predetermined limit which, if exceeded, will cause the power supply to shut down.
A circuit which either shuts down the power supply or crowbars the output in the event of an overvoltage condition.
