Power management systems for accepting adapter and solar power in electronic devices

摘要

The disclosed embodiments provide a power management system that supplies power to components in an electronic device. The power management system includes a system microcontroller (SMC) and a charger. During operation, the power management system accepts power from at least one of a power adapter and a solar panel. Next, the power management system supplies the power to components in the electronic device without using a converter circuit between the solar panel and the power management system.

主权项

1. A method for supplying power to components in an electronic device, comprising:
providing a power management system in the electronic device for accepting power from at least one of a power adapter and a solar panel; and using the power management system to supply the power to the components without using a converter circuit between the solar panel and the power management system, wherein an input voltage of the power management system is adjusted based on two output powers of the power management system, and wherein the input voltage is determined based at least on an inductor current of an inductor within a power converter in the power management system.
