C6672 Analog Power Reference Design

Other Parts Discussed in Thread: LM21215, LM10010, TPS56121

Hi,

I am starting a C6672 hardware design, but I'm having trouble finding an analog power reference design for this family.  Does this exist? Or is digital power the best/only option.  I also can't find the schematic for the TMDSEVM6678.  Can you point me to this?

Thanks

  • Hi,

    all the docs for the c6678 EVM:

    Power supply:

    Please have a look in the Hardware Design Guidelines Chapter 5.

    Kind regards,

  • Jamaal,

    There is an analog power solution that's in the plans but it is not ready with documentation at this time.  For now we are only providing the power solutions found within the HW design guidelines.  Once the analog power solution is ready it will be added to the HW design guidelines.

    Best Regards,

  • TI is releasing a power supply reference design based on the LM10010 and traditional analog based power supply controllers such as the LM21215 or the TPS56xxx and TPS40xxx families.  The LM10010 acts as an interface to the VCNTL interface of the C6672 and contains a 6-bit current DAC that directly connects to the feedback node of the external regulator to provide the output voltage control.  This implementation provides a more flexible solution for single-chip designs.  That reference design should be available from the TI power supply team.  Contact your TI power FAE and request details.

  • A reference design based on the LM10010 and the TPS56121/221 SWIFT Converter is now available on the TI website.  The following link will take you to a page with the schematic and the bill of materials as well as the test results.
