Hello infineon support 

Am looking for basic understanding on how to calculate the mosfet gate resistance. I found the design link here but it doesn't tell the calculation on how to design. 

Can you please help 

Thank you.

Still the calculation is missing in the link you shared, what is the formula ,  criteria, what value should I use, for 200khz what R should I use,

Am looking for some direct calculation, 

You explain me. there are so many links available in the internet. You share me the important points from the link you shared randomly as i dont see that is useful.

Hello @Sachin_alu ,

Can you please let me know which Infineon switching device and the device driver you are using. I can explain the summary of the gate resistance selection with those devices as an example.
