1. An aerosol delivery device, comprising:
a housing enclosing a reservoir configured to retain an aerosol precursor composition;
a first power-source terminal configured to connect a power source to the aerosol delivery device;
an atomizer configured to vaporize components of the aerosol precursor composition;
a switch coupled to and between the first power-source terminal and the atomizer;
a micro pump arranged to be operable between the reservoir and the atomizer to deliver aerosol precursor composition from the reservoir to the atomizer;
a driver circuit including a boost converter coupled to and between the first power-source terminal and the micro pump, the driver circuit being configured to drive the micro pump via the boost converter; and
a control component including processing circuitry configured to switchably control the driver circuit to drive the micro pump to deliver the aerosol precursor composition to the atomizer, the processing circuitry also being configured to switchably control the switch to connect the power source to the atomizer independently of the driver circuit and thereby power the atomizer independently of the boost converter to vaporize components of the aerosol precursor composition.
