Abstract

See full text

A voltage output circuit and an electronic cigarette are provided. The voltage output circuit includes a control chip and a step-down switch chip. When a first switch element turns on, the modulation signal output terminal of the control chip outputs a pulse modulation signal to a first control terminal of the step-down switch chip, and access between a first access terminal and a second access terminal of the step-down switch chip is established, based on the effective pulse modulation signal. The output voltage of the second access terminal is less than a system power voltage. The voltage output circuit and the electronic cigarette outputs the pulse modulation signal to the step-down switch chip by the control chip, and the step-down switch chip outputs a suitable driving voltage to the load, such as a thermal wire, the voltage output circuit with simplified structure is adjustable and improved.
