ABSTRACT:
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.
