Abstract
A method may include monitoring an input power supply, monitoring an inductance of an inductor of a boost converter, monitoring one or more other characteristics of the boost converter, and calculating a target peak inductor current based on the input power supply voltage, the inductance, the one or more other characteristics of the boost converter, and a target average current of the inductor during a switching cycle of the boost converter. A method may include monitoring an input power supply voltage, monitoring an inductance of an inductor of a boost converter, monitoring one or more other characteristics of the boost converter, and calculating an average current of the inductor during a switching cycle of the boost converter based on the input power supply voltage, the inductance, the one or more other characteristics of the boost converter, and a peak inductor current of the inductor.
