Available as a free download, the PI Expert version 7.1.5 power supply design software provides improved support for the company’s HiperPLC controller IC for offline resonant converters. The software permits the designer to choose from a variety of magnetic-core materials and sizes for both for the LLC and PFC stages.
The design spreadsheet allows for transformer design optimization for improved efficiency. It also accurately calculates the external resistor required to reduce no-load consumption in designs using LinkSwitch-II and LinkSwitch-CV product families in flyback topologies. And lastly, it expands the Help feature to include traditional Chinese language support. (Free — available now.)
