This user’s guide describes a power distribution
network (PDN), PDN-1A, using the TPS6594-Q1 and
the LP8764-Q1 devices to supply the J721E
processor with combined MCU and Main power rails.
The following topics are described to clarify
platform system operation:
- PDN power
resource connections
- PDN
digital control connections
- Primary (TPS6594-Q1) and secondary (LP8764-Q1)
PMIC static NVM contents
- PMIC
sequencing settings to support different PDN power
state transitions for an advanced processor
system
PMIC and processor data manuals provide recommended operating
conditions, electrical characteristics, recommended external
components, package details, register maps, and overall component
functionality. In the event of any inconsistency between any user's
guide, application report, or other referenced material, the data
sheet specification is the definitive source.
