Abstract:
1. A hybrid converter configured to convert an input voltage into an output voltage that drives an external load, the hybrid converter comprising: a) a first switching device controllable by a control signal; b) an inductor coupled to said first switching device and an output; c) a control circuit configured to receive feedback from said output for generation of said control signal to control said first switching device, wherein said control circuit comprises a first detection circuit configured to detect first and second output conditions, said control circuit being configured to operate said first switching device in a switch control region in response to said control signal when said first output condition is detected, and to operate said first switching device in a linear control region using mirroring devices when said second output condition is detected; and d) a second switching device coupled to said inductor, wherein said control circuit further comprises a second detection circuit configured to determine when said second switching device operates in said switch control region, said linear control region, or an off state.
