Dear friends
how to vary the duty cycle dynamically? on which parameter & which pin input the duty cycle will depend upon?

does anyone have detail pin description document of SG3525

 

Welcome to AAC. We ask that you post questions in a new thread, though, rather than placing them into an existing one - http://forum.allaboutcircuits.com/showthread.php?t=15236&page=5

The SG2535 may be obsolete. You might look for a part in current production.

 

Here is the datasheet:
