Abstract
A DC-DC voltage converter and associated control method capable of dynamically adjusting upper boundary of the inductor current are provided. The DC-DC voltage converter is electrically connected to an input terminal having an input voltage and an output terminal having an output voltage. The DC-DC voltage converter converts the input voltage to the output voltage, and the DC-DC voltage converter operates in a pulse frequency modulation mode. The DC-DC voltage converter includes an inductor and a converting circuit, which are electrically connected to each other. An inductor current flows through the inductor. The converting circuit adjusts the inductor current according to a setting signal so that the inductor current is less than or equivalent to an upper boundary of the inductor current.
