Xilinx’s Zynq UltraScale+ MPSoC line offers a high level of flexibility, with a range of devices that scale in complexity to suit a wide variety of applications. As such, the solutions that power the Zynq UltraScale+ must be equally adaptable to meet the power needs of a complex line.
This application note reviews four different variants of TI’s TPS65086x power management IC (PMIC) used to power the Zynq UltraScale+ (ZU+) line to provide a selection guide for comparing the different variants. The report also covers the value the TPS65086x PMICs bring to the overall system, and provide example power maps for each of the four main ZU+ power configurations.
The TPS65086x PMICs integrate 3 buck converters, 3 buck controllers, 4 LDOs, and 3 load switches in a small 8 mm × 8 mm VQFN package. The buck controllers allow customers to tailor their TPS65086x solution to the specific current needs of their system, which minimizes BOM size and cost. The integrated load switches enable extremely flexible power sequencing, allowing TPS65086x to fulfill the power requirements of the ZU+ line without external sequencers. The QFN package provides enhanced thermal performance at higher loads and simplifies routing, which reduces manufacturing time and cost. The TPS65086x also features the widest input voltage range on the market, from 5.6–21 V, which allows TPS65086x to support a variety of end applications across multiple battery types. The TPS65086x also supports the largest range of ZU+ devices, from ZU2CG all the way through ZU19EG. For more information on the different ZU+ devices, please refer to the Xilinx Zynq UltraScale+ site.
Furthermore, the TPS65086x family offers both pre-programmed and user-programmable variants to power the ZU+ family. The three pre-programmed variants simplify the design process for basic use cases, allowing you to directly implement the given power configuration with no modifications needs. For more unique power requirements, the user programmable variant gives you the freedom to fully customize the power solution to fit your system needs.
