Flex Power Designer
Sketch, simulate, configure and monitor your digital power system.
The Flex Power Designer software goes beyond converter configuration and provides an overview of the whole power system enabling you to define relationships across rails, including phase spreading, sequencing, and fault spreading, using the standard PMBus protocol.
The built-in simulation enables power-stage analysis to optimize tuning and visualize design behavior against your power requirements such as transient response, output impedance, and power dissipation.
Flex Power Designer is free to use after you register for a personal license. Using the application without registration is not permitted. If you are already registered on this site, please sign in where a download link is waiting for you.
Power Designer features include:
- System configuration and efficiency calculation of the entire power system including non-Flex devices.
- Configuration and simulation of the control loop, transient response and power dissipation.
- System functions for sequencing, tracking, paralleling and synchronization/phase spreading configuration.
- Easy configuration and monitoring of your digital power modules over a PMBus interface.
- SMBus tool and sample code bundled for full SMBus control and production programming.
- Easy reference design feature for Xilinx FPGAs, and integration with Xilinx Power Estimator for straightforward import of XPE files.
- The user guide is included with the installation software.
