To make its Flex Power Designer software easier to use for digital power system design, Flex Power Modules has added new features and expanded the products it supports. The new 3.2 version saves engineers time developing power systems and reduces the risk of any issues in the design.
Version 3.2 adds a time-saving digital conversion calculator that makes it easier for designers to calculate linear/Vout and linear/proportional values seen from monitoring data. The software also includes a new Display Address Resistor Suggestion feature that calculates suggested values for resistors SA0/SA1.
To enable more engineers to take advantage of Flex Power Designer, the software now provides test board support for Flex’s BMR480 and BMR490 DC-DC converters. It also adds the ability to monitor common parameters of other power supply suppliers’ products, increasing the designer’s flexibility. These parameters include at least input voltage, output voltage and temperature.
The new version contains all the features of earlier versions of Flex Power Designer. In particular, it includes thermal modeling added in v3.0. This allows designers to simulate thermal behavior, such as calculating hotspot temperatures and overall system efficiency, without building hardware.
Olle Hellgren, Director of Product Management and Business Development for Flex Power Modules, said: “Flex Power Designer is not just about converter configuration – it provides an overview of the entire power system, enabling designers to take advantage of the latest digital power technologies. The new 3.2 Versions make it easier to use and create efficient, error-free designs.”
With Flex Power Designer, designers and system architects can track or simulate the efficiency of the entire power system. They can define relationships across power rails, including phase spread, sequencing, and fault spread—meaning it’s easier for users to understand system-level behavior, resulting in faster time-to-market.
The software can configure and simulate control loops, and can directly configure and monitor digital power modules. SMBus tools and sample code are packaged with Flex Power Designer for complete SMBus control and production programming.
The simulation capabilities of Flex Power Designer enable power stage analysis to optimize tuning and visualize design behavior. Engineers can investigate how a system meets their design requirements by looking at specific metrics such as transient response, output impedance, and power dissipation.
