Hi,
I'd like to know if there are some reasonably quick ways to approximate the RC values for the error compensation network in the lm5119? If there are existing posts that answer this question, feel free to post a link.
From reading through some app notes, it looks like I can approximate the crossover frequency to be around 1/10~1/5 of the switching frequency? And then after that, I believe I can do a few small calculations and get my RC values.
Oh, one other question: would I need to switch to a type 3 compensation network if my load resistance is too low?
I don't have any experience with DC-DC design or control theory, so maybe there are some important things I'm missing? If anyone can summarize the best approach to a reasonable approximation that doesn't require solving 2nd order differential equations.
Thanks!
