Hello,
I m using UC2843 as PWM generator for PWM is from 0% to 100% duty cycle.
I assumed there is following relation between input voltage at I-sense and Output duty cycle
Input voltage at pin3 of UC2843D8 | Output Duty cycle |
1.00 | 0% |
0.90 | 10% |
0.80 | 20% |
0.70 | 30% |
0.60 | 40% |
0.50 | 50% |
0.40 | 60% |
0.30 | 70% |
0.20 | 80% |
0.10 | 90% |
0.00 | 100% |
But is not the case when I observed practical result ,It was different than I my assumption.
I don't found any relative formula in datasheet as well , which derive the output PWM duty cycle with respective input analog voltage at I-sense pin .
Please give suggestion what is formula ? where I find it ?
