Abstract: The heating engine control circuit includes a rail converter circuit and a gate driver circuit. The rail converter circuit is configured to convert a power supply voltage into a power signal based on a vaping enable signal, the vaping enable signal being a pulse width modulated signal. The gate driver circuit includes an integrated gate driver. The integrated gate driver is configured to control application of power to a heater of the non-nicotine electronic vaping device based on the power signal, a first enable signal and a second enable signal.

Abstract: A capsule for a heat-not-burn (HNB) aerosol-generating device may include a first frame, a second frame, a first heater, a second heater, and/or an aerosol-forming substrate. The first frame has a first interior face and a first exterior face. In addition, the first frame defines a first opening. The first heater may be secured to the first frame so as to cover the first opening. The second frame is connected to the first frame. The second frame has a second interior face and a second exterior face. Furthermore, the second frame defines a second opening. The second heater may be secured to the second frame so as to cover the second opening. The aerosol-forming substrate may be between the first heater and the second heater.
