摘要
A voltage and current triggered switch that turns on when a voltage across the switch reaches a turn-on voltage and that turns off when a current through the switch drops below a holding current. The switch features a Zener diode having a breakdown voltage. The Zener diode is connected to set the turn-on voltage of the switch to be the breakdown voltage of the Zener diode. Also provided is a step-down DC-DC converter comprising such a switch. Also provided is a system that has a tribo-electricity source or a piezo-electricity source, the provided step-down DC-DC converter and a load connected to an output of the stepdown DC-DC converter.
