ISL91211BIK-REF2Z Reference Design Board

ISL91211BIK-REF2Z Reference Board for Xilinx Spartan-7®

The ISL91211BIK-REF2Z reference board for Spartan-7 devices employs the ISL91211BIK multiphase PMIC and ISL80030 3A synchronous buck DC/DC converter. The ISL91211BIK is required for VCCINT, VCCBRAM, VCC_DDR, VCCAUX, and VTT, and it accepts 5V input from a plug-in AC/DC adaptor or DC power supply. The ISL80030 DC/DC converter supports VCCO and VCC_IO for 3.3V, 2.5V and 1.8V rails.

The PowerCompass™ tool helps you design your power supply in minutes, giving you tools to find Intersil parts that match your requirements, set up multiple rails if needed, perform high-level system analysis and generate reference design files.

PowerCompass supports over 200 FPGAs, including built-in templates for Xilinx FPGA families. You can even save time by importing Xilinx Power Estimator output files to get system efficiency and power dissipation projections.
