Abstract: An integrated circuit (IC) comprising: control circuitry operable to control: an external switch of a primary current path for an energy storage component of a circuit, wherein the external switch of the primary current path is external to the IC; a first internal switch of a secondary current path for the energy storage element, wherein the first internal switch is internal to the IC, wherein the IC is operable in: a first mode in which the first internal switch of the secondary current path is actuated to enable the secondary current path; and a second mode in which the external switch of the primary current path is actuated to enable the primary current path.
