Abstract
A step-down converter is presented. The step down converter includes a power stage having at least one phase, each phase comprising an inductor, a driver, and a clock source. The driver drives the power stage in a synchronous mode or in an asynchronous mode of operation with a minimum off time. When the output voltage approaches the input voltage of the converter, a duty cycle of the converter increases up to a value limited by the minimum off time. The clock source generates a first clock signal having a predefined pulse width. The driver generates a first stretchable clock signal having an adjustable pulse width and an adjustable period. Upon transition from the synchronous mode to the asynchronous mode the driver is configured to increase the adjustable pulse width and the period of the first stretchable clock signal.
