Part Number: UCC29002

Hi,

I have a nquestion regarding UCC29002/UC39002.

The datasheet says that the CSA gain is equal to R16/R15 and a high-frequency pole, configured with C13, is used for noise filtering. What's the criteria to choose high-frequency pole?

Thanks & BR,

Hi Ghasem,

The bandwidth of Current share loop is generally a few dozen to a few hundred Hz, so the high-frequency pole for noise filtering should be larger than 1KHz, I recommend it is better larger than 5KHz. You can just refer to the datasheet, it is 10KHz.

Regards,

Teng
