Abstract
A current mode converter includes a converter stage comprising a first switch, a second switch, an inductor, and a capacitor, and a digital-to-analog converter configured to convert a digital target current signal to an analog current signal. The current mode converter further includes a slope compensation circuit coupled to the digital-to-analog converter and is configured to convert the analog target current signal to a slope compensated analog target signal. A comparator is coupled to the converter stage and the slope compensation stage and is configured to generate and output a signal when a value of an actual analog signal is equal to a value of the slope compensated analog target signal.
