Abstract
Slope-compensated current mode DC-DC converters. Example embodiments are methods of operating a slope-compensated current mode DC-DC converter including asserting a pulse width modulation (PWM) signal in a switching period to couple an input voltage to the inductor; sensing an inductor current through an inductor to generate a sensed current signal; generating a slope compensation signal having a peak amplitude during the switching period; generating a slope offset signal based on a sum of a predefined threshold with a product of a duty cycle of the PWM signal and the peak amplitude; and de-asserting the PWM signal during the switching period based on the sensed current signal and the slope offset signal.
