• PI Expert is an interactive program that takes a user's power supply specifications and automatically determines the critical components (including transformer specifications) needed to generate a working switch mode power supply. Optimization choices for cost or efficiency are included to deliver designs that meet specific needs. The program reduces design time from days to minutes.
  
  
• PI Xls Designer provides design spreadsheet support for recently introduced Power Integrations ICs not yet included in the PI Expert Design Software tool, as well as providing a simplified spreadsheet approach for other PI products for advanced users who prefer a spreadsheet interface.
  
  
• PI Transformer Designer is a tool that generates detailed instructions needed by transformer vendors to construct a transformer based on designs created with PI Expert Design Software and PI XLS Designer. Intelligent shield selection is included to simplify the task of meeting EMI standards, with optimized bobbin pin assignment for ease of layout.
