The peak overcurrent behavior is similar to most other PWM controllers. If the peak current exceeds 1.0V, the active output pulse is terminated immediately. If voltage-mode control is used in a bridge topology, it should be noted that peak current ...

Adding the external ramp to the current feedback signal is the more popular method. From the small signal current-mode model [1] it can be shown that the naturally-sampled modulator gain, Fm, without slope compensation ...
