Abstract

A controller (200) for a DC-to-DC converter is configured to provide a PWM signal in a first state during a first time interval based on an input voltage less a voltage level representative of an output voltage of the DC-to-DC converter. The controller (200) may provide the PWM signal in the first state based on the time it takes to charge an energy storage element (202) of the controller (200) to a predetermined level. The controller (200) may also provide an estimator of a zero inductor current level in an associated inductor when the energy storage element (202) is completely discharged. The controller may also be a digital controller (200) that counts time pulse to provide the PWM signal. A DC-to-DC converter including such a controller (200) and associated methods are also provided.
