Voltage regulator with nonlinear adaptive voltage position and control method thereof

Abstract:

A voltage regulator has a switching circuit and a control circuit. The switching circuit provides an output voltage and an output current. The control circuit provides a switching control signal to the switching circuit to adjust the output voltage, such that the output voltage decreases with a first slope as the output current increases when the output current is less than a predetermined current, the output voltage decreases with a second slope as the output current increases when the output current is larger than the predetermined current.
