  • Electronic ballast
    Patent number: 9220159
    Abstract: An electronic ballast for lighting applications is disclosed. The electronic ballast comprises a first charge pump having an input capacitor (13) charged with a supply current drawn from a power source by application of a charging voltage to the input capacitor (13), the magnitude of the supply current being proportional to the magnitude of the charging voltage; and a voltage booster (16, 17) for generating a boost voltage, which is used to augment the charging voltage, thereby increasing the current drawn from the power source.
    Type: Grant
    Filed: February 6, 2012
    Date of Patent: December 22, 2015
    Assignee: NXP B.V.
    Inventors: Cornelis Josef Petrus Maria Rooijackers, Wilhelmus Hinderikus Maria Langeslag
