Abstract
A power architecture that uses an efficient intermediate power conversion stage between AC adaptor (and battery charger) and subsequent voltage regulators (VRs) (e.g., core VR) for processors for higher overall efficiency allowing for higher performance in a given thermal envelope and iso-system input power. Power losses from both the charger and the core VR are reduced by splitting the power as power to sustained high-power rails, and power to the rest of the platform power rails that have low residency in high-power states. The sustained high-power rails are placed under an intermediate power conversion topology which is directly powered by the adaptor. The rest of the rails along with charging of the battery are powered by the battery charger.
