Sorry, we haven't yet implemented it on PCB. Because we haven't finalized the circuit. right now we have done it on veroboard. this is our circuit diagram.

We solved this problem. We can vary our pulse width from 0% to 40%(approx). But we have another problem.
The PWM output frequency does not match with that calculated. Formula for frequency of generated PWM is f=1/(CT*(0.7*RT+3*RD).
when RT=15k, CT=1nF, RD=22 Ohm. Frequency should've been 95KHz...
I have created a simple PWM circuit using SG3525 to achieve 50% or more duty cycle. However the duty cycle gets saturated at only 30%( I have initially shorted the pin 1 and pin 9). Now when I have grounded pin 9 , it results in a sinusoidal output. Please tell me how to connect pin 9 and pin1...
