VR5510 compensation network component values.

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

Hi David,
Good Day!
Is any formula available for this compensation network calculation?

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.
