Hi TI Team，

1、The customer is asking what is the difference between TPS568215OARNNR and TPS568215RNN, and whether the two can be replaced and interused. It is also P2P, thank you.

2、What is the Out-of-Audio mode of TPS568215OARNNR? Help to analyze it, thank you.

3、At present, the customer has tested on the same board, the TPS568215RNN board works normally, and the TPS568215OARNNR board does not.

    Hi Ken,

    OOA operation is only applicable at lighter load condition. OOA feature allows the TPS568215OA to keep switching frequency above the audible frequency range. Other than that, there should not be any difference between the two devices. When you say the board does not work with OA version, can you elaborate what is happening?

    Thanks,

    Amod
