  • Circuits and methods for developing a regulated auxiliary output with an overwinding on a synchronous buck regulator
    Patent number: 6087817
    Abstract: Circuits and methods for regulating an auxiliary output with an over-winding on a synchronous buck regulator are provided. Though these regulators have produced regulated auxiliary outputs in conventional circuits, the regulation used in conventional circuits has not been maximized. This caused the auxiliary output voltage to vary with changes in load on the primary output as well as with changes in load on the auxiliary output. The present invention directly regulates the auxiliary output voltage of the synchronous buck regulator by adjusting the gate amplitude of a MOSFET switch located in the power loop of the auxiliary output.
