Abstract
A method and apparatus are provided for transitioning a power converter between a switched mode of operation and a linear regulator mode of operation. The power converter operates according to one or more intermediate modes of operation in which the switched mode and linear regulator modes cooperate to produce a shared power converter output. The power converter transitions between the various modes of operation in response to changes in circuit parametric conditions as defined by a series of state transition diagrams. Power converter output voltage is maintained in regulation during all modes of operation and transitions therebetween. The method and apparatus includes an integrated device that may be operated as a switch or a variable resistance device.
