BUCK REGULATOR WITH OPERATIONAL AMPLIFIER FEEDBACK FOR AN AEROSOL DELIVERY DEVICE
First Claim
1. An aerosol delivery device comprising:
- a housing structured to retain an aerosol precursor composition;
a heating element configured to convert electricity to heat and thereby vaporize components of the aerosol precursor composition; and
a control component coupled to and configured to controllably power the heating element, the control component including;
a buck regulator circuit coupled to the heating element, and configured to step down voltage and step up current from a power source to the heating element to thereby power the heating element; and
an operational amplifier circuit coupled to the heating element and buck regulator circuit, and configured to amplify an output voltage from the heating element to produce a higher voltage that is fed back to the buck regulator circuit,wherein the buck regulator circuit includes a power stage configured to step down the voltage and step up the current from the power source, and a feedback control circuit configured to use the higher voltage from the operational amplifier circuit to regulate an output voltage from the buck regulator circuit to the heating element.

Abstract
An aerosol delivery device is provided that includes a heating element configured to convert electricity to heat and thereby vaporize components of an aerosol precursor composition, and a control component coupled to and configured to controllably power the heating element. The control component includes a buck regulator circuit coupled to the heating element, and an operational amplifier circuit coupled to the heating element and buck regulator circuit. The buck regulator circuit is configured to step down voltage and step up current from a power source to the heating element to thereby power the heating element. The operational amplifier circuit is configured to amplify an output voltage from the heating element to produce a higher voltage that is fed back to the buck regulator circuit, which is configured to use the higher voltage to regulate an output voltage from the buck regulator circuit to the heating element.
