Other Parts Discussed in Thread: TIDM-BIDIR-400-12

Dear All,

One of my customer working on TI Bidirectional 400V - 12V Converter TIDM-BIDIR-400-12, they are going for PCB fabrication based on Geber available.

we have few clarity as below, please help to advise, i couldn't 

 able to see correct forum to post this hence i am posting in this place-if this is not proper place request to move this thread to proper forum.

1) Impedance required or not for this PCB, if required please advise impedance details.
2) Ref attached image Spacing 8 mil is required but existing is 6 mil, please advise why is it so & PCB vendor asking to update final gerber space more than 8mil.

Aravind.

    Aravind,

      Could you give more detail on question 2, please?  I'm not understanding exactly what is at issue here, I'm thinking it is that the pcb manufacturer wants to use 6mm spacing but the design is shown as 8mm?

      For the impedance, there is not a requirement for a controlled-impedance.  Typically this comes into concern for high-speed data paths, but not so for this design.  I'm still trying to get verification from the design files, but is there a particular area of the design this is a concern to you?

    Hello Aravind,
    I never received a response from you, so I am assuming this issue was resolved, is that correct?
