1 Introduction

In the Integrated Power Supply Reference Design for Xilinx® Zynq® UltraScale+™ ZU5EV and Artix® 7 FPGAs, the system input power source is DC 5-V, provided by a YU0506, 30-W 5-V 6-A AC/DC Power Adapter. For the VCCINT_VCU rail, this input voltage needs to be regulated down to 0.9-V (±3%) and sustain a current ranging from 500-mA up to 3-A depending on the complexity of the video processing tasks in the end application.
