  Modeling Analysis and Compensation of the Current-Mode Converter
  PDF, 189 Kb, File published: Sep 5, 1999
  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 c
