摘要： A multiphase power regulator includes a multiphase pulse width modulator, an output stage and an active transient response circuit. The output stage includes a high side transistor, a low side transistor and an inductor. The output stage is configured to supply power to a load responsive to signals generated by the multiphase pulse width modulator. The active transient response circuit is coupled between the output stage and the multiphase pulse width modulator and configured to detect the voltage level at the output stage and provide a signal to the multiphase pulse width modulator that is a function of the amplitude of the deviation of the detected voltage level from a target voltage.

摘要： Methods and apparatus for a power supply according various aspects of the present invention operate in conjunction with a voltage converter for converting an input voltage to an output voltage. For example, the converter may comprise a controller configured to generate a control signal and an integrated power stage. The power stage may include a segmented switch coupled in parallel between the input voltage and the output, and a driver circuit responsive to the controller and connected to the switches. The segmented switches may be parallel devices with separate gates, which may be activated independently. The driver circuit controls the switches according to the control signal to sequentially activate the switches in the switch circuit. For example, the driver circuit may activate a second switch following a predetermined period after activating a first switch, and the first switch and second switch may be activated sequentially and remain activated simultaneously.

摘要： Methods and apparatus for a multiphase power regulator according various aspects of the present invention operate in conjunction with an active transient response (ATR) system for applying a correction signal to a multiphase pulse width modulator. In the event of a transient, the ATR system may adjust the output of the pulse width modulator to quickly respond to load requirements. The output may be modified by adding pulses, blanking pulses, advancing pulses, and scaling pulses to one or more phases.

摘要： A wideband voltage regulator is configured to provide suppression of fast transients, which can include a boosting circuit and a sensing circuit. The boosting circuit can be suitably configured to boost the voltage regulator response, while the sensing circuit can determine when such a boost may be desired. Accordingly, the response of the voltage regulator can be accelerated to a fast load transient beyond the closed loop bandwidth limited response or the slew rate limited response of the voltage regulator. An exemplary voltage regulator can be configured with an active sensing circuit comprising a sensing amplifier with switch control outputs, and a boosting circuit comprising N stored charge sources, e.g.; boost capacitors, and (3N−1) switches that are configured to accelerate the voltage regulators response to a fast load transient beyond the closed loop bandwidth limited or slew rate limited response of the voltage regulator.
