Abstract
An embodiment switching converter includes a power stage that receives an input voltage for converting it into an output voltage and provides a load current to a load operably coupled to the power stage. The power stage includes an inductor carrying an inductor current and a digital controller configured to regulate the output voltage to a level close to a reference voltage using a pulse width modulated (PWM) signal supplied to the power stage.
