Hey,
Thank you so much once again !
I really appreciate you effort.
In your simulation output voltage is fixed, i was looking for variable output i.e. 3V to 8V so for that reason i wanted to change the duty cycle. I do not want to change the duty manually. it has to be ramped up via clock generator. Maximum allowed duty is 50%.
Duty cycle has to increase in order to variable output.
Thanks once again !

 

Output voltage could be like.


Duty should be like :

 

Output voltage could be like.

Are you telling me you don't know how to do that?
ETA: Never mind it is easy enough to demonstrate.

 

OK, here is what you asked for – I think.
