This reference design shown here is a complete power solution for the Xilinx Zynq 7020-484 device. The design uses three LMZ3 series modules to provide all the necessary rails to power the chip. The design also shows correct power-up sequencing solution for the power rails needed to power a Xilinx Zynq device. It is designed optimized to support a 12 V input. It features ease of use with integrated LMZ3 series power modules. The design is tested and ready to power up a Xilinx Zynq FPGA.
