Abstract
A step-up continuous-mode DC-to-DC converter with integrated current control, comprising a comparator for comparing a voltage signal output from the converter and a reference signal for generating an error signal and circuitry for generating a compensation ramp which generates a ramp signal which is added to a signal which is proportional to a current ramp that flows across the converter. The signal output from the comparator and the signal obtained from the sum are sent to an additional comparator, the output whereof, together with an oscillator signal, is used for driving a power transistor of the converter. A fuzzy logic control unit is interposed between the comparator and the additional comparator, the fuzzy logic control unit receiving at its input the error signal output by the comparator and emitting in an output signal which depends on the variation of the error signal over time to be sent to the additional
