Abstract:
A circuit and method for soft start of a system compare a feedback signal produced from an output voltage of the system with a ramp signal to generate a comparison signal, and enables the system once the comparison signal indicating the ramp signal reaches the feedback signal, such that the output voltage becomes active from a residual voltage toward a target level.
