Abstract
A converter and a method for controlling a converter are disclosed herein, in which the converter includes a converting circuit, a current sensing circuit, a digital-to-analog converting circuit, a slope compensation circuit and a comparator circuit. The slope compensation circuit is independent from the digital-to-analog converting circuit, and the slope compensation circuit exclusively generates an analog slope compensation signal. The comparator circuit compares an analog signal generated by the digital-to-analog converting circuit with the superimposition of the analog slope compensation signal and a current sensing signal generated by the current sensing circuit or compares the current sensing signal with the superimposition of the analog slope compensation signal and the analog signal to generate a comparator output signal for a control operation of the converting circuit.
