Patent attributes
A charger device comprises a Single-Input-Multiple-Output (SIMO) device including a first transistor connected to an input and a first end of an inductor, a second transistor connected to ground and the first end of the inductor, a third transistor connected to a second end of the inductor and a first output, a fourth transistor connected to the second end of the inductor and a second output, and a controller connected to the SIMO device. The controller is configured to cause the SIMO device to charge the inductor based upon an input signal using a first power source coupled to the input during a first time period and discharge the inductor to charge at least one of the first power source and a second power source coupled to the first output during an unused time period.
