Hi Team,
The datasheet recommend the ripple ratio is setting as 20%-40%. I am wondering if it can set as 50% if we pass the RA test, time domain test and bode plot in worse condition.
Below are articles that I find in E2E. It looks like 40 to 60% is a good balance for this ratio, but it is a just a rule of thumb. The outdated rule of thumb was set to 20 to 40% just so that the rating of output caps and inductor saturation current ratings and etc.
Regards,
Roy
Hello
You can use 50%.
Check to be sure that you will not hit current limit at your full load and high input voltage condition.
Thanks
