DS90UB954-Q1: POC current question

Part Number: DS90UB954-Q1

Dear Sir

The POC current of the DS90UB954TRGZRQ1 need to increased to 700mA or 1A. Is there a suggested solution? Thanks for help~

  • Hi AJ, 

    Why does the POC current need to be so high? It is not recommended to have >500mA current through PoC. You can refer to www.ti.com/fpd-link on PoC theory train, with the current increase, the dynamic noise in the PoC is increased as well which would impact the link reliability as well. You will also have trouble finding external because the current must be under the rated current or saturation current spec for the ferrite beads or inductors used in the PoC network.

    Thanks, 
    Sally 

  • Hi AJ, 

    Sorry for the mis-information earlier. We are working with other vendors for high current solutions, and if you'd like we can provide contact information to you via email. 

    Thanks,
