An aerosol delivery device is provided that includes power-source terminals to connect a power source to the aerosol delivery device, and a heating element to vaporize components of the aerosol precursor composition. The device includes a micro pump to deliver aerosol precursor composition from the reservoir to the heating element, and a driver circuit to drive the micro pump. The driver circuit includes a boost converter to step up voltage from the power source to the micro pump to thereby power the micro pump. And the device includes a control component with processing circuitry to control the driver circuit to switchably drive the micro pump to deliver the aerosol precursor composition to the heating element. The processing circuitry is also to switchably connect the power source to the heating element independent of the boost converter and thereby power the heating element to vaporize components of the aerosol precursor composition.
