... The fast fault input undergoes a special treatment. Since we want to implement skip cycle through the fast fault input on the NCP1396A, we cannot activate the soft−start every time the feedback pin stops the operations in low power mode. Therefore, when the fast fault pin is released, over the VCO lead as soon as the output voltage has reached the target ...
