Abstract
A charging circuit and a method with an inductor, an input to receive an input voltage, an output, and a switching means is presented. The switching means performs cycles where each cycle includes, switching the circuit such that the inductor enters into an energy charging state in which the inductor stores energy provided by the input voltage. When energy stored in the inductor reaches an energy threshold, the switching circuit operates such that the inductor enters into an energy discharging state in which the inductor provides energy to the output. The energy threshold is based on a predefined maximum energy storage current value and the time between cycles is based on a duration of the energy discharging state.
