摘要： Systems and methods for overcurrent protection in a battery charger are provided. For example, a method for overcurrent protection may include controlling a switching regulator to direct electrical current between the switching regulator and a battery port; sensing a voltage drop that is related to the electrical current passing between the switching regulator and the battery port; applying a first ramp voltage to the sensed voltage drop generating a modified sensed voltage drop; comparing the modified sensed voltage drop against at least one reference voltage; and when the modified sensed voltage drop exceeds the at least one reference voltage, changing operation of the switching regulator to protect the battery charger from an overcurrent state.

摘要： An embodiment of a power supply includes an input node operable to receive an input voltage, an output node operable to provide a regulated output voltage, an odd number of magnetically coupled phase paths each coupled between the input and output nodes, and a first magnetically uncoupled phase path coupled between the input and output nodes. Such a power supply may improve its efficiency by activating different combinations of the coupled and uncoupled phase paths depending on the load conditions. For example, the power supply may activate only an uncoupled phase path during light-load conditions, may activate only coupled phase paths during moderate-load conditions, and may activate both coupled and uncoupled phase paths during heavy-load conditions and during a step-up load transient.

摘要： An embodiment of a power-supply controller includes first and second circuits. The first circuit is operable to cause a first current to flow through a first phase of a power supply. And the second circuit is operable to cause the second phase of the power supply to operate in a reduced-power-dissipation mode for at least a portion of a time period during which a second current magnetically induced by the first current flows through the second phase.

摘要： An electronic system, a multiple charger configuration, and method of operating a multiple input, multiple charger configuration are disclosed. For example, a multiple charger configuration is disclosed, which includes a first battery charger circuit configured to receive to a first input voltage, and a second battery charger circuit configured to receive a second input voltage. A first switching transistor is coupled to an output of the first battery charger circuit, a system voltage output terminal, and a battery terminal configured to connect to a battery stack or at least one battery cell. A second switching transistor is coupled to an output of the second battery charger circuit and the battery terminal. Thus, the multiple chargers can be utilized in one system to charge or discharge a battery stack or at least one battery cell and thereby deliver power for a battery-operated system, product or device.

摘要： A battery charge system including an adapter node, a system node, a battery, a first isolation switch coupled between the adapter and system nodes, a second isolation switch coupled between the battery and system nodes, a boost converter, and a controller. The controller turns off the first isolation switch and turns on the second isolation switch during a battery mode, activates the boost converter when an adapter voltage is detected, turns off the second isolation switch when the system voltage rises above the battery voltage, and turns on the first isolation switch when the system voltage rises to an operating voltage level. The boost converter may then be turned off once in the adapter mode. The second isolation switch may initially be turned on partially at a low current level when the adapter is detected, and then turned fully on when the system voltage is at the operating voltage level.
