  • Start-up method and apparatus for boost converters
    Patent number: 10686377
    Abstract: There is presented a boost converter and an associated method for starting the boost converter. The boost converter includes an input terminal for receiving an input voltage, an output terminal for providing an output voltage, a low-side power switch and a high-side power switch coupled at a switching node, and a voltage regulator coupled to the high-side power switch. The boost converter is also provided with a controller for operating the boost converter in a start-up phase. In the start-up phase the controller controls the boost converter to generate an intermediate voltage and increase the intermediate voltage to a predetermined value. The intermediate voltage is then provided to the voltage regulator to obtain a drive voltage. The high side power switch is then driven to increase the output voltage linearly up to a start-up voltage.
