Hi,

As TPS2549 EVM figure, it only for this four DC/DC converter as red mark?

Or any used FB adjustable DC/DC converter? I used TPS51396A is ok, right? thanks!

    Hello,

    The TPS2549 detects the load current and generates a proportional sink current that can be used to adjust output voltage of the upstream regulator to compensate the IR drop in the charging path. This can be used with any DC/DC converter. These four listed are known to specifically work with the TPS2549. Please reach out to the TPS51396A to ensure that this will be compatible. From the TPS2549 side, this architecture will work.

    Thanks,

    Emma
