Texas Instruments (Unitrode)Switching power supply design.
Texas Instruments (formerly Unitrode) seminars are part of TI analog technical training during which they also update on their new controllers and other power management integrated circuits. They combine tutorial review of basic principles and "hands-on" design examples on various power conversion topics. Over time they have covered virtually all important switching power supply design topics and their archives provide excellent reference info for the SMPS designers. Here you will find seminar books from 1984 till present.
