TOPSwitch tips, techniques & troubleshooting guide

Answers to All Common TOPSwitch Technical Questions can be found in this application note, the TOPSwitch Data Sheets, the TOPSwitch Design Notes, and the TOPSwitch reference design/evaluation board documentation. The fastest path to TOPSwitch success is to read the TOPSwitch datasheets, AN-16 and this document carefully and completely before beginning the design. Detailed information on specific application circuits can be found in the Application Notes, Design Notes and Reference Design/Evaluation Board documentation listed below. Purchasing a Reference Design/Evaluation Board is strongly recommended and will dramatically reduce design, breadboarding, and debugging time. For information on specific subjects including PC design, Drain Voltage Clamping, and Recommended Transformer Inductance, find the appropriate section in the table of contents on the next page. For problems encountered in working power supplies, refer directly to the Troubleshooting Guide. For technical questions not covered by any TOPSwitch literature, fill out a copy of the TOPFAX form given at the end of this application note and FAX to Power Integrations, Inc.
