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 first control signal; b) a second switching device controllable by a second control signal; c) an inductor coupled to said first and second switching devices and an output; and d) a control circuit configured to receive feedback from said output for detection of first and second output conditions and generation of said first and second control signals, wherein said control circuit is configured to operate said hybrid converter in a switching mode when said first output condition is detected, and to operate said hybrid converter in a linear mode or a combination mode based on a control mode of said hybrid converter when said second output condition is detected, e) wherein said combination mode comprises one of said first and second switching devices being configured to operate in said linear mode and another of said first and second switching devices being configured to operate in said switching mode.
