描述

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.
