AEROSOL GENERATION DEVICE COMPRISING VOLTAGE CONVERTER

An aerosol generating device includes a battery, a heater for heating an aerosol generating material, a voltage converter, and a controller. An aerosol generating device is provided with a voltage converter that is arranged between a battery and a heater, and converts a voltage applied from the battery to a constant voltage to output a preset fixed voltage that is applied to the heater. A controller controls electric power supplied to the heater such that the preset fixed voltage is applied to the heater in a preheating mode.
