Fig. 5 shows the buck converter audio susceptibility in closed loop for different values of the external ramp. We can see the influence of the closed loop on the elimination of output noise. In current-mode control of the buck converter, for a duty-cycle greater than 50% (in practical applications even for a duty cycle lower than 50%), ...

Audio-susceptibility transfer functions without and with feed-forward gains along with required power-stage transfer functions are derived for peak current-mode controlled PWM dc-dc buck converter. The derived audio-susceptibility transfer functions are illustrated for given values of perturbation ratio using MATLAB.
