Power management for Xilinx Artix and Kintex FPGAs

Power management for Xilinx Artix and Kintex FPGAs

AnDAPT in Dublin, Ireland, has launched programmable power supply devices for the Xilinx Kintex and Artix FPGAs.

This follows-up on AnDAPT’s previous announcement of programmable power supply solutions for Xilinx’s Zynq family. 

AnDAPT has used its proprietary mixed-signal FPGA platform for the to cover the entire Xilinx Kintex and Artix device families, taking care of complexities such as rail consolidation, sequencing, and disparate power requirements.

The Kintex and Artix devices can require greater than 11 power rails and there are variations in the number and power requirements of each rail depending on the system and application requirements. AnDAPT power solutions meet or exceed Xilinx power performance specifications while achieving a reduction in solution PCB area by merging and reducing the number of devices used. All AnDAPT power management solution PMICs use the same silicon which can be configured to support the customer’s design requirements. Using one configurable device to support multiple designs simplifies customer inventory management.

Each 5mm x 5mm PMIC incorporates a single and a two phase DrMOS controller (up to 70A), multiple buck converters (10A/6A), high current LDOs (up to 2A), load switches (LDSW), four general purpose LDOs (200mA) and power management features including fault protection and sequencing.

Next on the AnDAPT roadmap are plans to release similar programmable power solutions for Xilinx Virtex, Versal, and Spartan families along with other FPGA/SoC vendors in the near future. 

AnDAPT has also created an intuitive software tool, WebAmp R.D., to provide ready-to-use PMIC solutions with optimum flexibility. These are based on Xilinx FPGA family device part numbers and use cases which have been defined by Xilinx.

Designers can use the PMIC devices as-is or modify rail sequencing, revise output voltages, alter maximum current per rail, or disable unused rails if desired. WebAmp R.D. provides all the necessary design documentation including design files, reference schematics, datasheets, BoM, and layout guides. If additional functionality is desired, such as system rails or glue logic, the generated design files can be used on AnDAPT’s WebAmP software tool for further modifications.

Reference designs can be used in the WebAmP tool for further customization including addition of other systems rails. 

“The benefits of these ready-to-use programmable products include faster time-to-market, reduced complexity, and greater reliability through fewer ICs. These solutions can be used as-is or further modified with our software design tools to create custom solutions,” said Bill McLean, CEO of AnDAPT. “The goal of these solutions is to enable faster product development, thus drastically reducing time to market, while ensuring high reliability and performance.”

The company is funded by Intel, Cisco, Atlantic Bridge and Vanguard.
