    Abstract: A multipath charger includes a first charging path, a second charging path, and a management module. A supply voltage is coupled through the first charging path and the second charging path to a battery. The management module provides the supply voltage and detects the operating state of the battery. The management module selectively enables the first charging path, the second charging path, or both according to the operating state of the battery, so as to charge the battery through the enabled charging path.

    Abstract: A switching mode charger capable of performing mode switching to adjust and output charging current for a battery or driving current for an external circuit element includes an input terminal, an output terminal, a Buck-Boost converter, and a controller. The Buck-Boost converter generates a voltage at the input terminal according to a voltage at the output terminal or generates a voltage at the output terminal according to a voltage at the input terminal. The controller dynamically selects an operation mode from a plurality of operation modes as an operation mode of the Buck-Boost converter according to at least one of the voltage change and the current change that are associated with the Buck-Boost converter, wherein the Buck-Boost converter dynamically performs mode switching according to the operation mode selected by the controller so as to adjust and output the charging current or the driving current.
