ABSTRACT:
A method of operating a switching power converter circuit having first and second transistors connected to an inductor, where a conduction control signal is selectively applied to the second transistor as a function of an operation of the first transistor during a conduction cycle. The decision on whether to provide a conduction control signal to the second transistor is made in one mode of operation as a function of the length of the first conduction control signal applied to the first transistor during the conduction cycle. In another mode of operation a comparison is made of the on-to-off conduction transition time of the second transistor to the length of time remaining in a conduction cycle after the first transistor ceases to conduct.
