The design of LED drivers poses a unique challenge in that LEDs must be driven with a constant current, rather than a constant voltage. PI Expert Suite v7.1 adds full design support for offline LED lighting applications.
SAN JOSE, Calif. (PRWEB) December 17, 2008
PI Expert Suite v7.1 consists of three components:
PI Expert: An interactive program that takes a designer's power supply specifications and 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 proprietary eShield™ EMI reduction techniques. Optimization 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: 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: A tool for viewing design files created with older versions of PI Expert. Explains Doug Bailey, Power Integrations' vice president of marketing: "Power Integrations focuses on making it easier for designers to create highly efficient power supplies. Typically, system developers go through a make/buy decision for their power supply needs – trading additional unit cost against development cost and risk. PI Expert arms system designers with the tools they need to take advantage of lower production costs by designing and building a custom power solution. The new version 7.1 software dramatically simplifies the design process, guiding the designer to a predictable and successful project outcome."
Bailey continues: "The design of LED drivers poses a unique challenge in that LEDs must be driven with a constant current, rather than a constant voltage. PI Expert Suite v7.1 adds full design support for offline LED lighting applications."
PI Expert Suite v7.1 is available now for free download, with fully supported English and simplified Chinese versions, at http://www.powerint.com/pi-expert. Transformer prototypes generated by the software may be ordered through PI's Rapid Transformer Sample Service (RTSS); a quick-start guide describing how to create a compatible design file is available at http://www.powerint.com/rtss.
