Sketch, simulate, configure and monitor your digital power system.

The 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.

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.

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.

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 will be included in the installation software.
