First Claim
Patent Images
1. An electronics system, comprising:
- an input power management component that receives an input power, determines an input voltage satisfies an input voltage threshold, and in response to the input voltage satisfying the input voltage threshold, activates a boost enabled signal;
a boost component that determines the boost enabled signal is activated, and in response to the boost enabled signal being activated, generates a boost output voltage using an input voltage; and
a step-down charging component that converts the boost output voltage to an output for charging a battery.

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.
