This page contains links to TI / Unitrode Corporation power supply seminar archives from 1983 to 1996. While during the last three decades most applicable standards and regulations have evolved, old Unitrode tutorials remain very useful in learning SMPS power supply design basics. For more recent 1997-2012 seminar handbooks go to - page 1.
