    Hello,

        A description of the PTPS659413F0+PTPS659411F0 can be found here.  The TPS65941212+TPS65941111 can be found here.  Generally, the TPS65941213 and the TPS65941212 provide a 3-phase output for VDD_CPU_AVS while the PTPS659413F0 only provided a 2-phase output.  We do have some documentation describing the differences but those would need to be provided in a different forum as they are under NDA at this time.

    Thanks and Regards,
    Chris
