The MxL7704 is initially offered in two options. The MxL7704-X has been optimized for powering the Xilinx® Zynq® Ultrascale+™ ZU2 and ZU3 MPSoCs. The bucks are pre-programmed to provide the core rail (0.85 V up to 4 A), DDR3L memory power (1.35 V), I/O and system power (1.8 V and 3.3 V). Sequencing is tailored to the unique needs of the ZU2 and ZU3 MPSoCs, offering accelerated time to market with Xilinx Zynq Ultrascale+ ZU2 and ZU3 devices. The MxL7704-A is designed to power a wide range of ARM® Cortex®-based processors (A7, A9, and A53) which use a more conventional sequencing scheme where the I/O rails power up first and core is last. The bucks provide the 1.2 V core rail, 1.35 V DDR3L power, 1.8 V and 3.3 V rails for I/O and system power.
