TPS650830: PGOOD CORRESPONDENCE

Len Cope
Prodigy 80 points
Part Number: TPS650830

Data sheet SLVSCF4A DECEMBER 2014 Table 6-57 refers to NODES V4, V5, V6, V7, V8, V9, V10, V13.

These nodes should be regulator outputs, but I can not see where in the document these nodes are defined. A simillar problem exists for Table 6-63. Where can I find the definition of these nodes?

    Hi, Len,

      Please see attached; for more details, please refer to Intel 's document "SkylakeKaby Lake Platform UY and Amber Lake Y Mobile Processor Lines Power Architecture Guide for the U and Y Processor Lines Rev 1.8 576068 Rev1p8.pdf".

    Data sheet SLVSCF4A DECEMBER 2014 Table 6-57 refers to NODES V4, V5, V6, V7, V8, V9, V10, V13

    I'm confused.

    Your Table has two names associated with each node. One for Premium, one for volume. I am not implementing these intel systems. This is a new design.

    So what node does V4_PGOOD map to in the IC. I need to know which Register Bits the PGOOD signals map to from PGVR1, PGVR2,PGVR3,PGVR4,PGVR5 and from VSA,VSB,VSC,VSD,VSE,VSF,VSG.

    Could you provide a link to the Intel document that you referenced? I could not find it.

    Hi, Len,

       Please contact Intel for the document; you may also need NDA for it.

    Who should I talk to about the TI Data sheet? 

    Data sheet SLVSCF4A DECEMBER 2014 Table 6-57 refers to NODES V4, V5, V6, V7, V8, V9, V10, V13.

    You tell me that these Nodes are Defined in an Intel Document that I may need an NDA for?

    This is not very convenient.

    Hi, Len,

      Please refer to the same datasheet "Figure 5-1. TPS650830 Volume Timing Diagram"; there is definition for the Nodes you are looking for.

    COMPG(V1.00S)

     

     

     

     

     

     

     

    The Figure 5-1 resolves all the signals except V6S,V8S,V11S; These appear to belong to COMPE (V3.3S), COMPF(V1.8S), and COMPG (V1.00S).

    Which is which I don't know.
