Abstract

The invention discloses a step-down integrated circuit and an electronic cigarette, wherein the step-down integrated circuit comprises a power supply module, a step-up charging module, a controller module, a driving module and a feedback operational amplification module which are integrated in an integrated chip, wherein the step-up charging module is used for boosting voltage input by an external power supply and charging batteries; the power supply module is used for supplying power to the controller module and the driving module; the operational amplification module is used for acquiring the sampling voltage of the output end of a peripheral power circuit and feeding the sampling voltage back to the controller module; and the controller module is used for controlling the starting or closing of the step-up charging module and the power supply module and controlling the driving module to output a PWM signal according to the sampling voltage input by the operational amplification module so as to drive the switching-on or switching-off of an external switch tube. The technical scheme disclosed by the invention realizes the step-down integrated circuit applied to the electronic cigarette, little space is occupied, and the interference resistance is high.

Description

Technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to a step-down integrated circuit and electronic cigarettes. Background technique [0002] E-cigarette is an electronic product that imitates cigarettes. The solution with tobacco flavor is heated and atomized into smoke for use by smokers. With people's requirements for product portability, highly integrated application circuits in electronic cigarettes are increasingly recognized by the market due to advantages such as small size and low cost. The voltage conversion circuit, power tube drive circuit and output sampling circuit of electronic cigarettes are important components. The step-down circuit in the existing electronic cigarettes takes up a lot of PCB space and has poor anti-interference ability, which is not conducive to the portable design of electronic cigarette products. . Summary of the invention [0003] The main purpose of the present invention is to provide...
