The Renesas Xilinx FPGA reference board is an expandable power supply designed to provide the various Xilinx power rails to the Xilinx Artix-7, Spartan-7, and Zynq-7000 families. The design uses the power source from the DC power supply or a plug-in AC/DC adapter to the barrel jack of this reference board.
The ISL91211AIK-REFZ reference board for Zynq-7000 devices employs the ISL91211AIK multiphase PMIC, ISL9123 low IQ buck-boost regulator and two ISL80030 3A synchronous buck DC/DC converters. The ISL91211AIK is required for VCCINT, VCCBRAM, VCC_DDR and VCCAUX. The ISL9123 supplies the VTT power rail, and the two ISL80030 DC/DC converters support VCCO and VCC_IO for 3.3V, 2.5V and 1.8V rails.
The ISL91211AIK provides four independent one time programmable (OTP) voltage defaults for each buck output. This flexibility supports an expandable and optimized power supply from a Xilinx high-end product to a low-end product. This reference board is designed specifically to solve the complex FPGAs and SoC devices. You can combine this reference design with your Xilinx FPGA or SoC motherboard platform.
