Flex Power Designer Tool: Now In Its Tenth Year

News

Flex Power Modules celebrates success of free free-to-use, downloadable configuration tool

In 2022, Flex Power Modules is celebrating the tenth anniversary of its free-to-use, downloadable Flex Power Designer tool. The tool has been updated with two major releases per year and new features currently planned include EMI filter design, support for further products recently released and additional functional enhancements.

The software was first released in 2012, in combination with the introduction of Flex Power Modules' digital DC/DC converters. The tool allows users to rapidly select catalogue products and virtually configure them into a system ‘power tree', set input rails and loads and then predict a wide range of performance results.

Over the years, the tool has been continuously developed to not only include prediction of basic performance, but also module and system efficiencies, power dissipation, temperature rises, output impedance, loop compensation effects, voltage excursions with transient loads and more. System functions such as sequencing and tracking, module paralleling and phase-spreading can be specified and evaluated.

Optimisation functions within the tool also allow the software to suggest phase-spreading arrangements of PoL converters and combinations of DC/DC products for best overall performance. A recent enhancement has been to integrate with Xilinx FPGA XPE files to enable automatic configuration of Flex Power Modules products to achieve optimum static and dynamic performance of the FPGA power rails and generation of a reference design.

Actual hardware is not required to run the tool and provide simulated results due to the inbuilt database of performance data, but through its GUI, the software can interface with real systems via PMBus to set and monitor parameters during system development and then program production parts with the chosen characteristics.

The installation package also includes the SMBus Tool which can be used for production configuration, and Flex Power Designer exports its configurations to an SMBus format file.
