Abstract: A voltage transient detector includes circuitry for transmitting electrical current through a light emitting diode and a fuse that is serially connected between the light emitting diode and a reference potential, such that the light emitting diode is illuminated when the fuse is not blown. The voltage transient detector also includes circuitry for transmitting a controlled amount of electrical current through the fuse in conjunction with an occurrence of a voltage transient at a voltage measurement location, where the voltage transient exceeds a set transient threshold voltage. The controlled amount of electrical current transmitted through the fuse causing the fuse to blow and the light emitting diode to turn off, thereby indicating occurrence of the voltage transient at the voltage measurement location.

Abstract: A step-down circuit has a switch connected in series between a direct current power supply and a load. A switch control circuit is configured to turn the switch off when the voltage across the load is higher than a predetermined first threshold and turn the switch on when the voltage across the load is lower than the first threshold. An energy storage unit is charged by the power supply when the switch is on and supply power to the load when the switch is off. An overcurrent protection circuit turns the switch off when the input current of the switch is higher than a predetermined second threshold.
