Claim 0:
1. An electronic cigarette comprising:
a voltage output circuit; the voltage output circuit comprising:
a control chip with a control signal input terminal and a modulation signal output terminal, the control signal input terminal receives a system power voltage through a first switch element, and is grounded through a first ground resistor; the first switch element configured to generate an enable signal to the control chip when being energized; and
a step-down switch chip with a first access terminal, a first control terminal, and a second access terminal; the first access terminal receives the system power voltage, the first control terminal is connected with the modulation signal output terminal of the control chip;

wherein when the first switch element is energized, the control chip receives the enable signal, and the modulation signal output terminal of the control chip outputs a pulse modulation signal to the first control terminal of the step-down switch chip, and an access is formed between the first access terminal and the second access terminal based on the effective pulse modulation signal at the first control terminal of the step-down switch chip; the output voltage of the second access terminal is less than the system power voltage;
the control chip further comprises a first power receiving terminal and a first ground terminal; the first power receiving terminal receives the system power voltage through a first filter resistor, and is further electrically connected with the first ground terminal through a first filter capacitor and a second filter capacitor, which are electrically connected with each other in parallel.
