Hi Michael,

please find my mail ID, safir.ahamed@valeo.com

Please answer my following doubts also in your mail.

Is this constant current Buck?

If yes, can we able to charge 2A Samsung mobile, 2.4 Apple and 3A std Type C with same design?

Hi Aham,

It is constant voltage buck.

The TPS25832-Q1 is focus on data communication, it don't have the DCP function but it can configure to CDP mode which mean can charge up to 1.5A in type A and 3A in type C.

The TPS25833-Q1 have the DCP function that can support Samsung,Apple and Type C with the same design.
