Central processing unit voltage rail that is independent of power state commands

Last updated:

Abstract:

Voltage regulators generate voltage rails that power a central processing unit (CPU). The CPU communicates power management instructions to a power supply controller that drives the voltage regulators. The power supply controller sets a voltage level of a voltage rail generated by a voltage regulator in accordance with a power management instruction received from the CPU. The power supply controller enables the voltage regulator to operate in discontinuous conduction mode (DCM) independent of power state commands from the CPU.
