Hi Team,
My customer are designing LM25117-Q1 & LM25119-Q1, We want to know is there have any theory that we usually selected between one twentieth and one fifth of the Fsw ?? (Source from LM25117-Q1 datasheet page.23)
Why is larger than 5% Fsw ?
I know larger than 20% Fsw will cause more unstable and too much noise on the Vout.
And does this "usually" selection crossover freq. between 5%~20% Fsw also apply to LM25119-Q1 ?
You can feedback me by mail kai.lai@ti.com directly, if you need more information from me! Thanks!
