Power design tool supports planar snapping


PI Expert, the online power supply design program from Power Integrations, now offers a planar magnetism generator, as well as a database of planar cores. With this update, PI Expert can generate an application-specific planar transformer design complete with PCB manufacturer-ready documentation and Gerber files.

The Magnetic Design feature of PI Expert V2.7 provides comprehensive planar transformer information including stack specifications, vertical and horizontal PCB construction, trace parameters, current density information and the resistance of the layer. The tool automatically incorporates user-specified creepage distances and clearance distances needed to meet safety isolation standards.

A comprehensive core and planar component database simplifies design and can also accept custom core geometries. PI Expert automatically optimizes the planar transformer design to match power supply specifications, incorporating additional winding layers and adjusting trace geometries as needed.

In addition to the planar magnetic constructor, PI Expert V2.7 adds support for the company’s entire InnoSwitch3 family of flyback switch ICs.
