Including design functionality for offline SSLDs, Power Integrations’ PI Expert Suite v7.1 power supply design software provides support for the LinkSwitch-CV and LinkSwitch-II families of primary-side-control switcher ICs. The PI Expert program takes a designer’s power supply specifications and automatically generates the electrical design and selects the critical components required to build a switched-mode power supply. It also contains an electrical and mechanical transformer design using eShield EMI reduction techniques, and optimization choices. The PI Xls Designer generates engineering and mechanical designs to assist users in prototyping the transformer and comes in a spreadsheet interface with support for recently introduced products not yet included in PI Expert. The PI Viewer lets the user look at design files created with older versions of PI Expert. The product is available for free download at http://www.powerint.com/pi-expert.
