TMS470MF03107: Could you please review the schematic design?

Part Number: TMS470MF03107
Other Parts Discussed in Thread: HALCOGEN
  • Could you please review the schematic design?

  • 111.pdf

  • Hi,

      We normally do not review customer's schematic as we do not understand customer's complete systems. With that said, from a high level I do not spot anything that is wrong in the schematic. 

    • Can you see what's wrong with the program?
