SUPPORTING XILINX FPGA's - ENPIRION POWER SUPPLY SOLUTIONS

October, 2006

As semiconductor design rules continue to shrink, FPGA function and speed continues to increase. This relentless increase in FPGA function and speed puts pressure on the supporting power supplies in terms of their performance, e.g. response time, noise, and ripple. The entire family of Enpirion switch-mode power supplies is ideally suited to meet these challenges. In addition to leading-edge performance, Enpirion power supplies are extremely easy to use and are also unmatched in terms of footprint, profile and performance. In support of its customers, Enpirion provides a User Guide and Practical Sample Circuits to further facilitate the ease of adoption.
