Charging Device

Abstract:

A charger device includes a Single-Input-Multiple-Output (SIMO) device and a controller. The SIMO device includes 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. The controller is connected to the SIMO device and is 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 discharge the inductor to charge a second power source coupled to the first output during a second time period.
