Power converter with slope compensation

A converter circuit, comprising:

• a power stage circuit coupled between an input and an output of the converter circuit, the power stage circuit including a control input;
• a driver circuit coupled to the control input;
• a feedback circuit comprising:
• an error amplifier coupled to a feedback voltage and a reference voltage;
• a comparator coupled to the driver circuit including a first input coupled to an output of the error amplifier and a second input coupled to an output of the power stage;
• and
• a slope compensation with slope adjustment circuit coupled to the output of the error amplifier and to the first input of the comparator, the slope compensation with slope adjustment circuit including a first transconductance amplifier coupled to an input voltage and configured to modulate the input voltage.

An integrated circuit device, comprising:

• a control circuit configured to generate a control signal to control a power converter circuit;
• a slope compensation circuit configured to provide a compensation signal to the control circuit, wherein the control circuit is configured to generate the control signal based at least in part on the compensation signal;
• a slope compensation adjustment circuit configured to dynamically adjust the compensation signal based on a rate of change of a sensed output current of an inductor selected to be coupled to the power converter circuit;
• and
• wherein the slope compensation adjustment circuit is configured to determine a downslope of the sensed output current, generate an emulated upslope based on the sensed output current, and modulate the emulated upslope with the downslope to produce the adjusted slope compensation signal such that the downslope approximates the emulated upslope.
