    摘要: A driving circuit for an N-channel Metal Oxide Semiconductor (NMOS) transistor can include a charge pump unit and a driver coupled to the charge pump. The charge pump can receive a source voltage and output an output voltage higher than the source voltage, where the source voltage is applied to a source terminal of the NMOS transistor. The driver receives the output voltage of the charge pump unit and converts the output voltage to a driving voltage operable for conducting the NMOS transistor.

    摘要: A supply topology comprising an AC to DC or DC to DC adapter and an electronic device with an active system, a battery, and an adapter controller implements closed-loop control of adapter output voltage to limit power consumption by the electronic device to a value related to maximum adapter power. The adapter couples a signal representing maximum adapter power to a control line connected to the electronic device and the electronic device couples an error signal representing the difference between instantaneous power consumption and adapter maximum power onto the same control line. The adapter adjusts its output voltage in response to the magnitude of the error signal. An adapter controller in the electronic device sets a limit for allocating current to battery charging from the signal representing maximum adapter power, with battery charging current approaching zero as instantaneous power consumption approaches maximum adapter power. The adapter controller adjusts the limit for allocating current to battery charging in response to new values of adapter maximum power associated with alternate adapters connected to the electronic device.

    摘要: A portable electrical device may include a DC to DC converter coupled to a common node, a load coupled to the common node, and a controller configured to control the DC to DC converter. The DC to DC converter may be configured to provide a charging current to a rechargeable battery from an adapter when the controller operates said DC to DC converter in a first adapter supply mode. The DC to DC converter may be configured to provide a battery supply current to the load via the common node when the controller operates the DC to DC converter in a second adapter supply mode. The adapter supply current and the battery supply current may add together at the common node to simultaneously provide a load supply current to the load in the second adapter supply mode.
