  • Charge pump voltage converter with charging current limiting
    Patent number: 8564985
    Abstract: A voltage converter comprises at least two capacitive charge pump stages, each comprising a capacitor, a charging switch through which a capacitor charging current is adapted to flow, and a control circuit for controlling the charging switch. wherein the control circuit for at least one charge pump stage comprises current limiting means for limiting the current through the charging switch. By limiting the current flowing through the switch, current spikes are avoided, which reduces high frequency distortion.
    Type: Grant
