I am designing a Boost DC_DC,detail:
1.VIN=2.5V,VOUT=25V;
2.L=10uH,C=2.2uF;
3.Max current in the ind is 1.3A;
4.EA's inputs are reference and feedback;and the output is 0~1.2V,which is compared to the sample value of the ind current plus slope_compensation;
If I ignore other Power loss,what's the value can I set the slope_compensation comparing to the EA output?I give the value is 0.4V,a third of the EA output,but I think it's too large.And if I want the VOUT=25V,how much is the value? I read Erickson,Robert W's book,it says ma=-1/2 m2,but I'm not sure how to use it.
