Texas Instruments (formerly Unitrode) power supply seminars are part of TI bi-annual analog technical training. In the process, TI also updates on its new controllers and other power management integrated circuits. The seminars normally combine tutorial review of basic principles and "hands-on" design examples on various power conversion topics. Although in my view, the latest seminars were not as useful as they used to be, over time they have covered virtually all main SMPS design topics. Their archives certainly provide excellent reference info for the SMPS designers. In this page you will find a list of seminar topics from 1996 till present. I used to provide direct links to all seminar topics. However, TI recently moved most of them into a new directory arranged by subjects and topologies, which now requires a registration. If you don't see a link here, you can go HERE to register and find these materials. For the manuals from 1983 to 1996 see our page.
