Hello friends,
I am using PWM to regulate voltage at the load end of my circut.
I want to take the output voltage to Analog Comparator or ADC whichever is convenient and if voltage changes from my fixed value ,
then I should be able to change the PWM duty cycle to bring my voltage back to previous constant value.
If the above thing can be done,
Please brief me about it..
thanks & regards
Ajay |

| Yes, can be done but I don't think the results are as good as with a 'real' regulator. Especially transient response will be ghastly. That last thing is less important if the load does not change its current draw too quickly too often. |
