Abstract: Systems, apparatuses, and methods may provide for power delivery circuit technology that includes a charger controller coupled to a battery output and an intermediate bus converter coupled to an adapter output, a system power input and the battery output, wherein the intermediate bus converter varies a voltage level of the system power input based on the battery output. In one example, the voltage level of the system power input is one or more of a percentage value or an absolute value greater than a voltage level of the battery output. Additionally, the charger controller may connect the battery output to the system power input in response to a turbo power event.

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.
