  • Advanced phase number control for multiphase converters
    Patent number: 8228049
    Abstract: A control circuit for generating a control signal to add phases to a multiphase voltage regulator. The control circuit includes an input for receiving an error correction voltage from an error amplifier of the multiphase voltage regulator and at least one output for providing a PWM control signal. Control circuitry generates at least one PWM control signal to add a phase to the multiphase voltage regulator responsive to a determination that the error correction voltage has exceeded a threshold level.
    Type: Grant

  • Configurable internal/external linear voltage regulator
    Patent number: 7612546
    Abstract: A voltage regulator includes a voltage source for providing an input voltage. The regulator includes circuitry responsive to the input voltage for generating a regulated output voltage. The circuitry enables selection of one of internal linear voltage regulation or external linear voltage regulation for generating the regulated output voltage.
