PI Expert Suite v7.0 consists of three components:
- PI Expert: 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: a simplified spreadsheet approach to power supply design for advanced users and those who prefer a spreadsheet interface, along with support for recently introduced products not yet included in PI Expert.
- PI Viewer: a method for viewing design files created with older versions of PI Expert.
