Dialog Semi and Xilinx Team Up to Power Visual AI Solutions

September 03, 2021 by Gary Elinoff

Xilinx opts for Dialog’s power management ICs to power its Kria K26 artificial intelligence (AI) modular system.

Dialog’s DA9062, DA9130, and DA9131 are power management ICs (PMIC) that deliver up to 21.5 amps and are readily customizable via the company’s SmartCanvas graphical user interface (GUI). They will be employed to provide the specialized power required by Xilinx’s Kria adaptive system-on-modules (SOMs), which are purposed for visual AI applications.

The Kria K26 System-on-Module

The Kria K26 SOM features an XCK26 system on a chip (SoC) based on the Xilinx’s Zynq UltraScale+ MPSoC (multiprocessor system on a chip) architecture. The device has been optimized to serve in edge vision applications that require flexibility to adapt to diverse and fast-changing requirements. Xilinx targets the K26 at applications such as machine vision, industrial robotics, smart city, and AI/ML computing. It is designed to be plugged into a carrier card with solution-specific peripherals, such as Dialog’s PMICs.

As described by Kirk Saban, Vice President, Product, and Platform Marketing at Xilinx, “Dialog Semiconductor’s highly integrated PMICs have allowed us to deliver a credit card sized Kria K26 SOM with a highly efficient power system enabling Xilinx customers to fast track their vision AI applications in the retail analytics, security, smart camera, and machine vision markets.”

  • The DA9062-A operates with input voltages of 0.3V to 5.5V with a total output capability of 8.5A. There are 4 buck converters, of which two can be connected for a 5A dual-phase configuration. Four LDOs provide up to 300mA each. Switching frequency is 3MHz

  • The DA9130-A features an input voltage range of 2.5 V to 5.5 V with a dual-phase output voltage range of 0.3V to 1.9 V. It switches at 4MHz

  • The DA9131-A has an input voltage range of 2.5 V to 5.5 V. There are two dual-phase, 5A outputs with an output voltage range of 0.3 V to 1.9 V. Switching speed here is 4MHZ

All three feature AEC-Q100 Grade 2 qualified versions, with DA9130-A and the DA9131-A available additionally in industrial/commercial versions.

Dialog has been active in the field of PMICs. We have reported on the DA914X-A series, a series of Sub-PMICs, and the DA923X family.


GreenPAK from Dialog

Xilinx’s AI starter kits employ Dialog’s GreenPAK configurable mixed-signal ICs to create a custom solution encompassing power sequencing, supervisory control, and power-on reset. GreenPAK is easily configured for the implementation of a low cost, small footprint, power systems that provides the greatest possible efficiency.

As stated by Dialog’s Tom Sandoval, Senior Vice President, GM Automotive Business Segment. “Xilinx’s market leading Kria adaptive SOMs to take full advantage of Dialog’s flexible/scalable power solutions in combination with GreenPAK.” He goes on to state that “Our close collaboration with Xilinx has enabled a high performance, fully programmable vision AI platform that will greatly benefit customers.”
