  • Light load detector circuit for inductive DC-DC converter
    Patent number: 10958174
    Abstract: A power converter and method to detect a light load condition at an output of the power converter are presented. The power converter may have an inductor and a resistive element connected between an input of the power converter and an input of the inductor. The power converter may have a first chopping unit to generate a chopped voltage signal at an output of said first chopping unit, wherein the chopped voltage signal is generated by chopping an inductor voltage at the input of said inductor based on a duty cycle of the power converter. The power converter may have a reference current source, wherein the reference current source and a replica resistive element are arranged in series. The power converter may have a comparator unit to generate, based on the reference potential and based on the chopped voltage signal, a signal indicative of said light load condition.
