MAXREFDES1238: Scalable, Single Input, 6 Output, Power Solution for the Versal ACAP Platform


Reference Design Disclaimer See the  Important Notice and Disclaimer  covering reference designs and other Maxim resources.


Size, cost and complexity are some issues facing Power Electronics Engineers when it comes to designing a power solution for high power FPGAs. The Mulltiphase Controller, Multiphase Powerstage and MAX77812 are just some of the Maxim ICs which eliminate these issues when completing a high power, multiple output design. The combination of the highly integrated Multiphase Controller with the Multiphase Powerstage ICs eliminates the need for many external components when designing for a high current rail. While our highly efficient MAX77812 PMIC easily manages the lower power rail requirements.

In this design a single 12V input supplies a circuit which outputs 6 separate rails ranging from 500mW to 130W.

The design is specified to meet the XILINX Versal ACAP AI Core Series UC1/3 requirements. The design layout is also optimized for the Versal ACAP IC.
