Dear team,

Does the line spacing of 15 mil or line spacing of 5 mil in TSP23881 layout have any effect?

Is it okay for us to have a line spacing of 5 mil?

Or do you have any concerns?

Many Thanks,

Jimmy

Hi Jimmy, for the reference designs and EVMs that I have done, the rule of thumb I follow is 20V/mil in general for the PCB. So I would double check the max worst case voltages on those lines and calculate the separation using the above ratio. Thanks!
