  • MULTIPLE OUTPUT POWER SUPPLY INCLUDING ONE REGULATED CONVERTER AND AT LEAST ONE SEMI-REGULATED CONVERTER
    Publication number: 20020167299
    Abstract: A power supply, including a regulated switchmode converter, a PWM controller, a semi-regulated converter, and a linear regulator. The regulated switchmode converter is for converting an input voltage to a first output voltage. The PWM controller is responsive to the first output voltage, and includes an output terminal coupled to a control terminal of a switch of the regulated switchmode converter. The semi-regulated switchmode converter is for converting the input voltage to an intermediate output voltage, and includes a switch having a control terminal coupled to the output terminal of the PWM controller. The linear regulator is coupled to the semi-regulated switchmode converter and is for converting the intermediate output voltage to a second output voltage.
