Overview: Integrated switchers can do
much more than you may have thought possible. Buck ICs can bend over backwards
to form Buck-Boost configurations (and vice versa). Boost ICs are automatically
configurable as Sepic, Cuk or Zeta converters. But to realize their full
potential, we must learn to first conceptualize in fairly abstract terms.
The seminar will present a unique understanding of all the standard topologies
and also provide practical tips and design examples to implement the various
morphs.
