Dialog Semi offers array of low-cost power solutions for Zynq UltraScale+ MPSoCs (and Spartan-7 FPGAs too!)

One of life’s realities is that the most advanced semiconductor devices—including the Xilinx Zynq UltraScale+ MPSoCs—require multiple voltage supplies for proper operation. That means that you must devote a part of the system engineering effort for a product based on these devices to the power subsystem. Put another way, it’s been a long, long time since the days when a single 5V supply and a bypass capacitor were all you needed. Fortunately, there’s help. Xilinx has a number of vendor partners with ready, device-specific power-management ICs (PMICs). Case in point: Dialog Semiconductor.

 

If you need to power a Zynq UltraScale+ ZU3EG, ZU7EV, or ZU9CG MPSoC, you’ll want to check out Dialog’s App Note AN-PM-095 titled “Power Solutions for Xilinx Zynq Ultrascale+ ZU9EG.” This document contains reference designs for cost-optimized, PMIC-based circuits specifically targeting the power requirements for Zynq UltraScale+ MPSoCs. According to Xilinx Senior Tech Marketing Manager for Analog and Power Delivery Cathal Murphy, Dialog Semi’s PMICs can be used for low-cost power-supply designs because they generate as many as 12 power rails per device. They also switch at frequencies as high as 3MHz, which means that you can use smaller, less expensive passive devices in the design.

 

It also means that your overall power-management design will be smaller. For example, Dialog Semi’s power-management ref design for a Zynq UltraScale+ ZU9 MPSoC requires only 1.5in2 of board space—or less for smaller devices in the MPSoC family.

 

You don’t need to visualize that in your head. Here’s a photo and chart supplied by Cathal:

The Dialog Semi reference design is hidden under the US 25-cent piece.

 

As the chart notes, these Dialog Semi PMICs have built in power sequencing and can be obtained preprogrammed for Zynq-specific power sequences from distributors such as Avnet.

 

Cathal also pointed out that Dialog Semi has long been supplying PMICs to the consumer market (think smartphones and tablets) and that the power requirements for Zynq UltraScale+ MPSoCs map well into the existing capabilities of PMICs designed for this market, so you reap the benefit of the company’s volume manufacturing expertise.

 

Note: If you’re looking for a PMIC to power your Spartan-7 FPGA design, check out Dialog Semi’s DA9062 with four buck converters and four LDOs.

Hello,

 

Is there such a solution/recommendation for the Artix7?

Hi @dpaul24,

The Dialog DA9062 should also be a good fit for Artix 7, depending on the exact artix device you plan to use etc. 

If you like, we can put you in contact with the Dialog Semi folks and they will stear you in the right direction. 

Thanks,

Cathal

Hi @cathal,

 

I also wanted to point out that the DA9062 is the PMIC of choice for many Zynq-7000 All Programmable SoC devices, such as the one found on the Avnet MiniZed evaluation board:

What a versatile power part!
