Abstract:
1. A power control circuit that controls the amount of charge delivered from a battery to a load, comprising: a comparator that compares a voltage across the load with a desired operating voltage; a control module that generates one or more control signals for controlling the rate at which a power switch transfers charge between the battery and the load responsive to an output from the comparator; wherein the control module generates one or more control signals that increase the rate at which the power switch transfers charge between the battery and the load responsive to an output from the comparator indicating that the voltage across the load exceeds the desired operating voltage, and wherein the control module generates one or more control signals that decrease the rate at which the power switch transfers charge between the battery and the load responsive to receiving an output from the comparator indicating that the voltage across the load is less than the desired operating voltage.
