Title:
ELECTRONIC CIGARETTE DRIVE CIRCUIT AND ELECTRONIC CIGARETTE
Document Type and Number:
WIPO Patent Application WO/2018/028599
Kind Code:
A1
Abstract:
An electronic cigarette drive circuit comprises an MCU, a boost-buck drive circuit, and a power supply. The boost-buck drive circuit is connected to the MCU, and the MCU and the boost-buck drive circuit are separately connected to a circuit of the power supply. The boost-buck drive circuit comprises a first half-bridge drive circuit and a second half-bridge drive circuit that are separately connected to the MCU. The first half-bridge drive circuit and the second half-bridge drive circuit are connected by means of an inductor. One end of a first sampling circuit is connected to an input end of the power supply supplying power to the first half-bridge drive circuit, and the other end of the first sampling circuit is connected to the MCU. One end of a second sampling circuit is connected to an output end of the second half-bridge drive circuit, and the other end of the second sampling circuit is connected to the MCU. By using the solution, a great driving power can be outputted, a voltage of the electronic cigarette drive circuit can be adjusted, and performance of an electronic cigarette product can be improved.
