1. An aerosol generating device comprising:
a battery;
a heater configured to heat an aerosol generating material;
a voltage converter configured to output a preset fixed voltage by converting a voltage applied from the battery to a constant voltage; and
a controller configured to determine whether the heater is operating in a preheating mode, and control electric power supplied from the voltage converter to the heater such that the preset fixed voltage is applied to the heater in the preheating mode to reach a preset preheating target temperature,
wherein a period of time for preheating the heater in the preheating mode is determined to be constant based on an amount of power required for the temperature of the heater to reach the preset preheating target temperature and the preset fixed voltage being applied to the heater in the preheating mode.
