TPS650830: PGOOD CORRESPONDENCE

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".

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.

VOLUME NODE TABLE 6-57, 6-58	FIGURE 5-1	FROM TABLE 3-5 PREMIUM

V4	COMPD(VCCIO)
V5	VR5 (V5ADS3)
V6	VR3 (V33ADSW)
V7	COMPA(V3.3_PCH)
V8	VR2 (V1.8A)
V9	COMPB(V1.8U_2.5U)
V10	VR4(V1.2U)
V11	VR1 (V1.00A)
V12	VR1 (V0.85) TP650831
V13		VTT(LDO1)
V6S
V8S
V11S
	COMPC
	COMPE(V3.3S)
	COMPF(V1.8S)
	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.
