Abstract
In one implementation, an input power management component receives an input power, and determines whether an input current and voltage satisfies predetermined thresholds. A boost component generates a boost output voltage using the input voltage if the input current satisfies a predetermined current threshold, and a step-down charging component converts the boost output voltage to a voltage for charging a battery and system power management.
