The ISL8024DEMO2Z demonstration board is a low-noise power module that powers the high-speed data converters on AMD RFSoCs. The ISL8024DEMO2Z integrates five output voltage rails into a high-density plug-in power module. It offers very low output voltage ripple with dual LC filters. It has very tight load-point voltage regulation with remote voltage sense to compensate for board copper loss and interconnection voltage drop. Digital programmability is also available as an option. LC filters at each input rail alleviate the EMI interactions between different rails.

Features

Three input voltage sources: 5.0V, 3.3V, and 1.8V
Five output voltages: ADC_AVCC, ADC_AVCCAUX, DAC_AVCC, DAC_AVTT, and DAC_AVCCAUX
PMBus interface that can digitally control the voltage set-point and margining of the DAC_AVTT rail
All rails have differential point-of-load (POL) voltage sensing
Additional low-pass filter to reduce output voltage ripple related to the switching regulator while maintaining high efficiency
