Title:
VOLTAGE OUTPUT CIRCUIT AND METHOD, AND ELECTRONIC CIGARETTE
Document Type and Number:
WIPO Patent Application WO/2019/165742
Kind Code:
A1
Abstract:
A voltage output circuit and method, and an electronic cigarette. The voltage output circuit comprises a power source (300) and a step-down circuit (200). The step-down circuit (200) is connected to the power source (300) and configured to convert the power supply voltage of the power source (300) to an operating voltage, wherein the operating voltage is less than or equal to the limit discharge voltage of the power source (300), and the operating voltage is the voltage of a working device (400) connected to the voltage output circuit during normal operation. According to the voltage output circuit and method, and the electronic cigarette, the power supply voltage of the power source (300) is converted to an operating voltage by means of the step-down circuit (200), so that even if the power supply voltage of the power source (300) is reduced, or even reduced to the limit discharge voltage, the working device (400), such as an atomizer, can still operate at a normal operating voltage, thereby solving the problem in the prior art that the electronic cigarette may be unable to operate as the battery power decreases.
