6. Slope Compensation
An unconditional instability of the inner current loop exists for any fixed frequency current-mode converter operating above
50% duty cycle. Therefore, to guarantee current loop stability, the slope of the compensation ramp must be greater than
one-half of the down slope of the current waveform. The ramp voltage for slope compensation is as follow,
