  • Power supply controller
    Patent number: 10256724
    Abstract: Exemplary embodiments are directed to a power controller. A method may include comparing a summation voltage comprising a sum of an amplified error voltage and a reference voltage with an estimated voltage to generate a comparator output signal. The method may also include generating a gate drive signal from the comparator output signal and filtering a signal coupled to a power stage to generate the estimated voltage.
    Type: Grant
    Filed: February 1, 2016
    Date of Patent: April 9, 2019
    Assignee: QUALCOMM Incorporated
    Inventors: Zeljko Grbo, Aleksandar Prodic, Francesco Carobolante
