Circuitry for a plurality of induction elements for an aerosol generating device is disclosed. Each of the plurality of induction elements is for inductive heating of one or more susceptors for heating aerosol generating material in use. The circuitry includes a plurality of driver arrangements, each one of the plurality of driver arrangements being arranged to provide, from an input direct current, an alternating current to a respective one of the plurality of induction elements in use. Each driver arrangement includes one or more first transistors each controllable by a switching potential to substantially allow current to pass therethrough in use. The circuitry also includes a converter arranged to step up an input potential to provide the switching potential in use, the converter being common to each of the plurality of driver arrangements.
