I am using the ADuM3190 in a DC-DC converter as isolation errror ampliifer.
How can i achieve soft-start using the EAOUT pin of the ADuM3190? I tired using RC at the +IN pin. But until the VDD2 reaches 3V the output is oscillating and sometimes shooting up.
If i use EAOUT2 pin, the soft-start of the PWM IC is working, but from 3V until whic point there is no soft-start.
How can i achieve soft-start from 0V to the full output voltage.
Why is the performance different for the two outputs?
The load & input transient performance for the two outputs is also different with the same compensation circuit.
How can i achieve the soft-start without affecting stability?
Or would you recommend any other equivalent IC which will provide this function?
