Power Integrations has released a new generation of its dynamic power supply design tool that promises to deliver shorter design times for switched mode power supplies (SMPSs) built with its scalable power conversion ICs.

The PC-based software, PI Expert Suite v5.0, automates the design of flyback, forward converter and buck topology power supplies, and utilizes an intuitive user interface and new productivity enhancing features.

The software suite consists of three major components, including PI Expert design software, PIXls designer and PI viewer.

The PI Expert design software is an interactive program that takes a designer's power supply specifications and automatically determines the critical components needed to generate an energy efficient switch mode power supply. These include transformer specs, bulk input capacitance, and the selection of the correct power conversion IC.

The new PI Expert design software version has also undergone major redesign and expansion. Enhancements include an improved user interface, and a new Design Wizard that guides the user to the best circuit topology. It also adds an interactive schematic diagram featuring GUI circuit blocks for ease of user modification, a design navigation tree for simultaneously browsing multiple designs, and new design forms to determine resistor values to implement overvoltage and under-voltage protection and to set external current limit.

The PIXls designer offers spreadsheet design support for the recently released products as well as for users who prefer a simplified spreadsheet approach, while the PI viewer allows the viewing of designs created with previous versions of the PI Expert.

The CD ROM software suite contains a complete library of the company's latest data sheets and application notes, as well as a mirror copy of Power Integrations' web site. The PI Expert Suite v5.0 is offered free of charge and is available for download from the company's web site.
