Abstract
A charger circuit includes a first path regulator, a path switch, and a second path regulator. The first path regulator is configured to generate a first regulation current based on an input voltage and an input current. The path switch is configured to pass or block a first charging current in response to a control signal. The first charging current is generated based on the first regulation current. The second path regulator is configured to generate a second regulation current based on the input voltage and the input current. At least one of the first charging current and a second charging current is used to charge a battery. The second charging current is generated based on the second regulation current. The second charging current is transferred to the battery without passing through the path switch.
