Hello
I'm using LM25118 in my project. I'm providing 9-30V input and output is 30.5V at 2A. Iripplemax= 0.9A f=294.6599KHz
In datasheet for all the calculation both buck and buck boost mode calculation is given. With my requirement of current design I need to use buck boost configuration. Is it enough if I calculate all parameters using buck boost?
Why the buck mode equations given?
I thought that it is for the case when input of this IC more than output. Whether what ever I assumed is right.
I have done calculation for both.
When I calculated I1 limit for buck boost it satisfies condition but for buck it is not. I have to undergo iterative method if both calculation required for buck boost?
I wanted to know that if i am using buck boost mode whether buck boost calculation is enough.
Please help me out in this concern.
