0 V @ 6 A output, 2% tolerance (<3% required) 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 Table 1.
Measured results Spec Total Loss (Iout =max all rails) Power delived Vout ripple Value 6.
0 84 10 Units W W mVppk on each rail Rev.
