Power Solutions for Xilinx FPGAs

Xilinx has selected Maxim as the preferred power supplier for the latest high performance FPGA reference designs, including Zynq Ultrascale+, Artix-7, Spartan-7, Kintex Ultrascale and Virtex Ultrascale. Our newest power solutions deliver the performance, ease of use, and flexibility required for today's FPGA-based designs.

In addition to stringent regulation requirements, FPGA power designs require all rails to be properly synchronized and monitored for power faults. Our programmable multichannel power management supervisors, sequencers, and voltage trackers provide the functionality needed to complete your high-performance power management system.

Power Rail Design



Individual Power Rail Selection

Use Xilinx's Power Estimator spreadsheet to get a list of all power supply rails and a rough estimate of the current consumption for each. Xilinx also provides XPower tools built into their ISEM design environment that provide a more accurate power requirement based on resource utilization, clock frequency, and toggle rates. Click within the following selector tables to view recommended regulators for your rail:

Single Output Voltage Regulators for Core, RAM, MGT, and Auxiliary Rails (VOUT 0.9V to 3.3V)

Low Noise MGT Rails
Powering a multi-gigabit transceiver (MGT) rail requires special design considerations due to requirements for very low ripple and noise (10mV peak-to-peak maximum).

Noise/ripple is not specified in a regulator datasheet. Meeting a noise/ripple spec is achieved through multiple means–for example, board layout, control architecture, and external components.  Any analog PWM controller/regulator that operates in fixed frequency, PWM mode all the time (no skip mode)  is a good candidate for driving an MGT power rail.   LDOs also generally meet the MGT rail noise/ripple specification.

Select a product from the table above to find regulators to power MGT rails. Be sure to take note of the special design considerations for ripple/noise in layout and component selection.
