Abstract:
1. A switching regulator comprising: an input terminal configured for receiving an input current; a first capacitor with a positive end electrically connected to the input terminal, and a negative end grounded, the first capacitor being charged by the input current when the input the terminal receives the input current; a first electronic switch electrically connected to the positive end of the first capacitor, and turned on when the charge on the first capacitor increases to a predetermined value; a second capacitor with a positive end electrically connected to the first electronic switch, and a negative end grounded, the second capacitor being charged by the input current when the first electronic switch is turned on; a second electronic switch electrically connected to the first electronic switch, and turned on when the charge on the second capacitor increases to a predetermined value; and an output terminal electrically connected to the second electronic switch, the output terminal configured for outputting the input current when the second electronic switch is turned on.
