    摘要: A switching regulator has a number of switchable power circuits, a number of inductive elements each being in series with a respective power circuit, and a number of resistors each being in series between a respective inductive element and a common node. A hysteretic comparator circuit has a first input coupled to the common node, and an output coupled to control the switchable power circuits. A number of sampling circuits each being coupled to provide a resistor voltage of a respective resistor as an input to the hysteretic comparator circuit is also provided. The hysteretic comparator circuit responds to each pair of resistor and common node voltages using the same hysteresis thresholds.

    摘要: In accordance with an embodiment of the disclosed matter, a voltage regulator may supply power to one or more components within a computer system. The voltage regulator may include an inductor and a current detection circuit to detect current through the inductor. When the inductor current is detected to be above a threshold, the voltage regulator operates synchronously. When the inductor current is detected to be below the threshold, the voltage regulator operates non-synchronously.

    摘要: A voltage regulator includes an output stage, an amplifier and a slew rate control circuit. The output stage furnishes an output voltage, and the amplifier interacts with the output stage to regulate the output voltage. The slew rate control circuit interacts with the output stage to establish a first slew rate for the regulator when the regulator is powering up and a different slew rate for the regulator after the regulator has substantially completed powering up.

    摘要: A dynamic switching voltage regulator includes a load indicator, power switches, and a controller. The load indicator generates a load signal responsive to different output load conditions of the regulator. The controller receives the load signal and drives the power switches at a first switching frequency. The controller changes the switching frequency to a second frequency in response to a change in the load signal.
