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 current mode charger controller for controlling a DC to DC converter. The current mode charger may include a first error amplifier having an output coupled to a common node. The first error amplifier may be configured to compare a first signal representative of a charging current provided to a rechargeable battery with a maximum charging current and provide a current control signal in response to the comparison. The current mode charger controller may further include an internal compensation network coupled to the common node, and a comparator configured to compare an inductor current signal representative of an inductor current through an inductor of the DC to DC converter with a compensation signal. The need for any external compensation for the current mode charger controller may be eliminated.

摘要： A subranging analog-to-digital converter wherein, during a first phase, a differential analog input voltage is held by a track and hold circuit and is fed to a low resolution flash ADC to provide the most significant bits (MSBs). During a second or recirculating phase, flash ADC output segments corresponding to the MSBs are fed to respective current switches of a current DAC to produce complementary analog conversion currents that are coupled to the track and hold circuit. In response to the complementary DAC currents, the output stage of the track and hold circuit is used to subtract a voltage corresponding to the MSBs from the input voltage without the use of a separate subtractor. Further, the DAC current switches provide equal currents during the first or MSB phase to deactivate the subtraction function during the first phase.
