Optimized PMIC for Low Power FPGAs and SoCs MxL7704
The MxL7704 is a five output Universal PMIC optimized for powering a broad range of low power FPGAs, DSPs, and microprocessors from 5V inputs.
The MxL7704 includes four synchronous step-down buck regulators that provide system, memory, I/O and core power from 1.5A to 4A. An on-board 100mA LDO provides clean 1.5V to 3.6V power for analog sub-systems. This PMIC utilizes a conditional sequencing state machine that is flexible enough to meet the requirements of virtually any processor. The MxL7704-X and MxL7704-A are the first standard configurations to be launched based on this unique universal PMIC.
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 (0.85V up to 4A), LPDDR3 memory power (1.35V), I/O and system power (1.8V and 3.3V). Sequencing is tailored to the unique needs of the ZU2 and ZU3 MPSoCs.
The MxL7704-A is designed to power a wide range of ARM® Cortex®- based processors such as 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 1.2V core rail, 1.35V LPDDR3 power, 1.8V and 3.3V rails for I/O and system power.
This PMIC offers a high 1MHz to 2.1MHz switching frequency and a current mode architecture with internal compensation. These features enable very fast transient response to line and load changes without sacrificing stability or board space. It operates over an input voltage range of 4V to 5.5V and includes fault protection features such as input under-voltage, overvoltage, overcurrent protection, and thermal protection.
