2.15.3 Power Supply Sequencing and Power Modes
Sequencing for the power supplies follows the recommendations for the Zynq Ult device. The
power configuration programmed into the International Rectifier IRPS5401MTRPBF devices controls the
power supply sequencing. An end-user may utilized the PMBUS on the carrier-card or utilize the Zynq
Ult MPSoC interface to the PMBUS to power down individual rails to implement the different power
modes supported by the MPSoC.
Sequencing is needed for board power up, as well as entering and exiting different power modes. There are
3 power domains, PS LP (Processing Subsystem Low Power), PS FP (Processing Subsystem Full Power)
