Hi,
When VPRE = 4.2V @ 455KHZ, how can we calculate the compensation network component values.
Please let me know what the RCOMP, CCOMP, and CHF values are
Hello,
I hope all is great with you. Thank you for using the NXP communities.
We highly recommend using the values mentioned on the datasheet. Unfortunately they are tested and guaranteed using VPRE=3.3/5V.
Based on previous design guidelines, I would like to recommend the following values based on your requirements.
RCOMP=2.2KΩ
CCOMP=16nF
CHF=330pF
Please note that I do recommend to perform your own tests.
I hope this information helps.
Regards,
David
Hello,
You may find the formula at the previous versions of the datasheet. As mentioned before, we highly recommend using the values predefined on the current datasheet.
