Internal soft-start increases the pulse width during power-up and maintains pulse width matching for the high and low outputs throughout the start-up cycle. Typically, the soft-start duty cycle varies beginning from 5-10% ramping up to about 50% over 1000 cycles.  The\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eAUIR2085S\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003einitiates a soft start at power up and after every overcurrent condition.
