i think u all have been tensed for switching the mosfet.....its not a big deal....just u need to do is...
*generate a sawtooth waveform, can be generated by timer's output through charging and discharging of capacitor.....
*compare the sawtooth waveform with the DC value ....this generates a PWM output..
*this PWM output from comparator can be fed into the gate of MOSFET
*and nothing but it just works...
i have tried it.....
any comments on this post is warmly welcomed
thanks

| The concept you have applied is really greate.....I think same thing can be done using digital logic gate also.......it becomes more simpler.

i too tried this but instead i used a pwm output from the timer circuit (after generating pwm output from timer) but i couldn't take the feedback from the timer....will try this...any ways great work
Added after 1 minutes:
i would be grateful if you could send me the CKT
