Abstract
The present disclosure provides a driving method, a driving assembly, and an electronic cigarette having the same. The driving method includes: acquiring an output voltage of a power supply of the electronic cigarette; calculating a duty ratio meeting a preset power using the detected output voltage and an effective resistance of a heating assembly; and driving a current circuit of the heating assembly of the electronic cigarette to switch on or switch off according to the duty ratio, so that the heating assembly operates under the preset power. According to the present disclosure, the cost of the electronic cigarette can be lowered, a relatively stable TPM (Total Particulate Matter) value can be output, and the size of the electronic cigarette can be reduced.
