UCC28070A: accuracy of VSENSE

Guru 29690 points
Part Number: UCC28070A

Hi Team,

My customer considers to use UCC28070A for his application however it seems accuracy of VSENSE voltage doesn't meet their specification.



Their requirement is less than ±1% at worst so they considers to put external amplifier and high-precision reference instead.
I would like to send simplified schematic that describe above in offline and would like you to check if it is reasonable method or not.
Could you send me e-mail to the following address?
yaita-k@clv.macnica.co.jp

Your support would be appreciated.

Best Regards,
Yaita / Japan disty
