Hello Eileen,

Thanks for looking into this part. The BQ25756 can't support dual phase interleave.

Let me know if you have any other questions.

Best Regards,

Hi Ethan,

Hello Eileen,

Neither the BQ25756 or the BQ25750 support dual phase interleave.

The BQ25756 can be run in parallel with itself however.

Why does the customer need dual phase interleave?

it is used in 1kw MPPT application, we would like to do dual phase

I see BQ25750 have fsw-sync pin, if add an external clock, BQ25760 can support interleave?

Hello Eileen,

None of the BQ2575X support dual phase interleave.

It is possible to run the BQ25756 in parallel with each other, but I don't think this work for MPPT.
