Abstract
According to one embodiment, an integrated circuit (IC) is disclosed. The IC includes a package, a die mounted within the package, circuit components mounted on the die, and a voltage regulator mounted on the die to supply power to the circuit components.
Claims16
A computer system comprising:
- a central processing unit (CPU);
- and
- a chipset, coupled to the CPU, having a voltage regulator integrated on the die to supply power to chipset circuit components, the voltage regulator comprising:
- an amplifier to provide a regulated output voltage;
- a voltage reference circuit, coupled to the amplifier, to provide an adjustable reference voltage to the amplifier based upon a received configuration signal;
- a first transistor, coupled to the output of the amplifier, to regulate the output voltage;
- a second transistor coupled to the output of the amplifier;
- and
- a third transistor coupled to the output of the amplifier, wherein one or more of the first, second and third transistors are activated based upon the output current flow from the amplifier.
