Abstract: In an example, a system includes a single-output flyback/LLC converter adapted to be coupled to an alternating current (AC) power supply. The system also includes a buck regulator coupled to the single-output flyback/LLC converter. The system includes a first LED including an anode coupled to the single-output flyback/LLC converter and a cathode coupled to the buck regulator. The system also includes a second LED including an anode coupled to the single-output flyback/LLC converter and a cathode coupled to a ground terminal.

Abstract: Described examples include a system having a power source having a first output terminal and a second output terminal and a controller. The system also has a selective charger coupled to the controller, the selective charger configured to couple, in response to instructions from the controller, the first output terminal of the power source to a first node that is configured to be coupled to a first terminal of a selected battery cell of two or more serially coupled battery cells, and couple the second output terminal of the power source to a second node configured to be coupled to a second battery terminal of the selected battery cell.
