Split-switcher voltage regulator architecture |
摘要 |
A power management system that can include an application processor and a power management unit (PMU). The PMU can generate a regulated output voltage based on control signals generated by a switch control module of the application processor. The control signals can be determined based on a comparison of monitored voltages within the application processor and a generated reference voltage. The reference voltage can be generated based on fed back signals corresponding to the control signals. The application processor and the PMU can be formed utilizing different size manufacturing process technologies. For example, the PMU can be formed utilizing a larger size manufacturing process technology than the application processor. |

1. A power management system, comprising:
an application processor including a switch control module configured to generate a control signal based on a comparison of a reference voltage and at least one of a plurality of monitored voltages within the application processor, wherein the reference voltage is generated based on a feedback signal corresponding to the control signal; and a power management unit (PMU) configured to generate a regulated output voltage based on the control signal, wherein the PMU and the application processor are formed utilizing different size manufacturing process technologies. |
