Patent ID: 8912938

Claim:
A converter, comprising: a converting circuit configured for converting an input voltage into an output voltage; a current sensing circuit configured for sensing an input current corresponding to the input voltage or an output current corresponding to the output voltage to generate a current sensing signal; a digital-to-analog converting circuit configured for converting a digital signal, which is generated according to the output voltage, into an analog signal; a slope compensation circuit independent from the digital-to-analog converting circuit, the slope compensation circuit configured for generating an analog slope compensation signal exclusively to be superimposed on the current sensing signal or the analog signal; and a comparator circuit configured for comparing the analog signal with the superimposition of the analog slope compensation signal and the current sensing signal or configured for comparing 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.
