  • Dynamic control of power converter output voltage slew rate
    Patent number: 6989612
    Abstract: A system and method is provided for dynamically controlling output voltage slew rate in a power converter. Preferred embodiments of the present invention operate in accordance with a power converter including at least a slew-rate control lead (a trim lead, a control lead, etc.), an error-amplifier circuit located therein, a slew-rate circuit, and a controller electrically connected to the power converter and adapted to dynamically control the converter's output voltage slew rate through the transmission of a slew-rate signal. In one embodiment of the present invention, the slew-rate circuit is external to the power converter and electrically connected to both a trim lead of the power converter and to the controller. In another embodiment of the present invention, the slew-rate circuit is internal to the power converter and electrically connected to both a control lead of the power converter and to the error-amplifier circuit.
