Abstract
An adaptive slope generator can include a current mirror configured to receive a multiplied current that varies as a function of an output voltage and a switching frequency of a switching current. The output voltage can characterize the switching current provided to a load coupled to an inductor. The current mirror can also be configured to receive an oscillation current. The oscillation current can have an amplitude that corresponds to the switching frequency of the switching current. The current mirror can be further configured to generate an output current substantially equivalent to the product of the oscillation current and the output voltage. The adaptive slope generator can also include a ramp generator configured to generate a compensation signal based on the output current. The compensation signal can have a sawtooth shape and a slope that varies as a function of the output voltage.
