Abstract :
As current-mode conversion increases in popularity, several peculiarities
associated with fixed-frequency, peak-current detecting schemes have
surfaced. These include instability above 50% duty cycle, a tendency
towards subharmonic oscillation, non-ideal loop response, and an increased
sensitivity to noise. This application note attempts to show that the
performance of any current-mode converter can be improved and, at the same
time, all of the above problems can be reduced or eliminated by adding a
fixed amount of "slope compensation" to the sensed-current waveform.
