    摘要: A multiphase voltage regulator provides a voltage to an output terminal. The voltage regulator includes N parallel switches providing respective current phases that are added together to generate a total current for a general load coupled to the output terminal. The voltage regulator also includes N inductive circuits. Each inductive circuit is between an output node of a respective switch and the output terminal. A sense circuit adds the voltages in each of the output nodes of the N switches. An amplifier circuit has an input receiving the added voltage, and outputs a current proportional to the total current. A controller with two pins reads the total current. The two pins are connected to the inputs of the amplifier.

    摘要: A method is provided for controlling a converter of the multiphase interleaving type. According to the method, there is detected when a change of a load applied to an output terminal of the converter occurs. When detected, all of the phases of the converter are simultaneously turned off by the generation of suitable PWM driving signals. The PWM driving signals are controlled so as to force the turn-on of the phases at the same time and to zero a time phase shift of driving of the interleaving type of the PWM driving signals. The interleaving of the driving time phase shift is recovered and a normal operation of the converter is restarted. A controller for controlling a converter of the multiphase interleaving type is also provided.

    摘要: The voltage regulators are capable of limiting undershoots of the output voltage without having a similar effect on overshoots because of the presence of a current cancellation network, input with the reference voltage and coupled to the second input of the error amplifier. This current cancellation network is adapted to inject into the second input a unidirectional compensation current of the first and second currents injected by the first and second feedback networks, respectively, the compensation current being determined by time variations of the difference between a replica of the output regulated voltage and the reference voltage and/or by time variations of the reference voltage.
