Abstract
A digital slope compensation apparatus and method for a switched-mode power supply use a sensor for sensing and generating an analog inductor current (i) of the switched-mode power supply, a comparator () for generating a trigger signal according to a comparison of an analog current threshold level and the analog inductor current (i), and a pulse width modulator (PWM) for controlling the operation of a switched-mode power supply, wherein the pulse width modulator (PWM) is arranged to be triggered by the trigger signal of the comparator. A first analog to digital converter is arranged for converting an analog output voltage (V) of the switched-mode power supply into a digital output voltage, means are arranged for transforming the digital output voltage into a digital current threshold level (i) and a digital to analog converter is arranged for generating the analog current threshold level according to the digital current threshold level (i).
