Abstract
A soft-start generation system is configured to generate a soft-start voltage. The soft-start generation system includes sawtooth circuitry configured to generate current having a sawtooth waveform and staircase circuitry configured to generate current having an ascending staircase waveform. A ramp-up current may be generated that is a combination of the sawtooth current and the staircase current. The ramp-up current may continuously ramp up to a predetermined current level. The soft-start voltage may be generated based on the ramp-up current.
