Power Integrations has introduced an updated version of its power supply design software, PI Expert.

The software now supports the Linkswitch-CV and Linkswitch-II families of primary-side-control switcher ICs, and includes comprehensive design functionality for offline LED drivers.

PI Expert Suite v7.1 consists of three components.

PI Expert is an interactive program that takes a designer’s power supply specifications, automatically generates the electrical design and selects the critical components required to build a cost-effective switched-mode power supply.

The tool also provides a detailed electrical and mechanical transformer design, using PI’s eShield EMI reduction techniques.

Optimisation choices stressing cost and efficiency are included, to help designers target specific needs.

The program reduces design time from days to minutes.

PI Xls Designer is a hands-on 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.

The tool generates detailed engineering and mechanical designs, to assist users in prototyping the transformer.

PI Viewer is a tool for viewing design files created with older versions of PI Expert.

PI Expert Suite v7.1 is available now for free download, with fully supported English and simplified Chinese versions.
