Abstract
A converter circuit includes a power stage circuit configured to convert an input voltage received by an inductor to an output voltage provided at an output; a control circuit configured to generate input pulses to control the power stage circuit; a slope compensation circuit configured to provide a compensation signal to the control circuit for overcoming a sub-harmonic oscillation in the converter circuit, wherein the control circuit is configured to generate the input pulses based at least in part on the compensation signal; a slope compensation adjustment circuit configured to determine a rate of change of a current at the inductor and to provide a slope compensation adjustment signal based on the determined rate of change; and a modulation circuit configured to modulate the compensation signal with the slope compensation adjustment signal to produce the adjusted slope compensation signal.
