Charging Device

A charger device comprising:

• 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;
• and
• a fourth transistor connected to the second end of the inductor and a second output;
• a charger having a first end connected to the first output and a second end;
• and
• a controller that is operatively connected to the SIMO device and configured to cause the SIMO device to charge the inductor using a first power source coupled to the input during a first time period and to discharge the inductor to charge a second power source via the charger during a second time period, wherein the second power source is connected to the second end of the charger.

A charger device comprising:

• a second transistor connected to a second input and the first end of the inductor;
• a third transistor connected to ground and the first end of the inductor;
• a fourth transistor connected to a second end of the inductor and a first output;
• and
• a fifth transistor connected to the second end of the inductor and a second output;
• and
• a controller that is operatively connected to the MIMO device and configured to cause the MIMO device to charge the inductor during a first time period using at least one of a first power source coupled to the first input and a second power source coupled to the second input, and to discharge the inductor to charge a third power source coupled to the first output during a second time period.
