DESCRIPTION
The Analog Devices Power Module provides a proven robust design for powering Xilinx 7 series
devices. Designed to meet the tolerance and sequencing guidelines set forth by Xilinx, the Analog Devices Power
Module provides a highly optimized controller based design utilizing the ADP1850 dual output synchronous buck
controller. This design uses four dual channel ADP1850 controllers to achieve 8 independent outputs. It utilizes
an innovative clocking scheme deriving the clock signal from the switchnodes of the first rails to power up. This
reduces channel interaction and beat frequencies that would be present without synchronization and eliminates a
costly external clock source. It meets recommended start up sequencing for Xilinx 7 series devices: Vccint ->
Vccaux -> Vccaux_io -> Vcco
