Abstract
A current-mode controller comprises an inductance element, at least one semiconductor switch coupled to the inductance element, and a ramp compensator coupled to sense an indication of current through the inductance element and coupled to control the at least one semiconductor switch that senses current during on-time of the DC-DC converter, infers current during off-time of the DC-DC converter, and determines a slope compensation signal based on the sensed and inferred currents.
