1. An aerosol delivery device comprising:
an atomizer configured to produce an aerosol from an aerosol precursor composition;
a power source connected to an electrical load that includes the atomizer, the power source comprising a supercapacitor configured to provide power to the electrical load, wherein the supercapacitor is a hybrid capacitor, wherein the power source further comprises:
a DC-to-DC converter connected to the supercapacitor, between the supercapacitor and electrical load;
a snubber circuit connected in parallel with the supercapacitor and thereby forming a parallel combination, the DC-to-DC converter being connected in series with the parallel combination of the snubber circuit and supercapacitor; and
a diode connected to, and between, the DC-to-DC converter and electrical load; and
a microprocessor configured to operate in an active mode in which the microprocessor is configured to direct power from the power source to the atomizer and thereby control the atomizer to activate and produce the aerosol.
