Tool/software:
Hello TI,
Excel calculation tool mentioned in this post may have some issues.
1. 500 kHz frequency in row 18 is not on the list.
2. If I enter values taken right from the example in the official specification (chapter 9.2.1.1 Design Requirements), the tool comes with substantially different power inductor value.
I think either calculations presented in chapter 9.2.1.1 are simplified too much (e.g. switching diode forward voltage is not considered) or there is some mistake in the excel tool.
