Abstract
A SMPS has a switching circuit, an adding circuit and a comparing circuit. The adding circuit adds the output voltage feedback signal of the SMPS to the output current feedback signal of the SMPS to provide a combined feedback signal. The comparing circuit compares the combined feedback signal with a reference signal and provides a comparing signal. And the power switch of the SMPS is controlled based on the comparing signal.
