Power Integrations today published Version 8.5 of its popular power supply design productivity software, PI Expert Suite. This latest release adds support for the company’s new HiperLCS family of high-frequency LLC converter ICs, as well as the recently-introduced TOPSwitch-JXfamily of integrated offline switcher ICs.

PI Expert Suite significantly shortens and simplifies the design process by generating a complete schematic of the power supply, including an optimized power transformer designand a completebill of materials. In addition to support for the latest PI product families, the Version 8.5 update includes thermal calculations to optimize heatsink performance and provides PCB layout recommendations forthe device and package type chosen.The new version also features an updated component library that includes fuses, fusible resistors, shunt regulators, optocouplers, and heatsinks.

Comments Doug Bailey, vice president of marketing for Power Integrations: “PI Expert Suite is well known to designers of flyback power supplies for greatlysimplifying the design process, reducing the number of prototype cycles, and accelerating time to market. With the release of Version 8.5, these same benefits are now available to designers of resonant converters.”

Bailey continues: “HiperLCS is the most highly integrated LLC converter available, enabling extremely compact designsdue to its high operating frequency, whichallows the use of small transformers and capacitors. PI Expert Suite Version 8.5 seamlessly guides users through the design process, particularly the unique challenges of designing transformers for high-frequency operation.”

The software is now available in two versions –32-bit and 64-bit. The 64-bit version takes advantage of larger system memory and faster processor speeds to expedite the design optimization process.

PI Expert Suite is available in English, Traditional Chinese, Simplified Chinese, Korean, Japanese, and Russian languages and can be downloaded now at Transformer prototypes resulting from the use of this software can be ordered through Power Integrations’ Rapid Transformer Sample Service (RTSS); a quick-start guide describing how to create a compatible design file is available at
