  80V Synchronous 4-Switch Buck-Boost Controller Delivers
  Hundreds of Watts with 99% Efficiency – Design Note 521
  Keith Szolusha and Tage Bjorklund Introduction
  A DC/DC converter’s efficiency and component temperature are important considerations in high power applications where high current could overheat the catch
  diode used in an asynchronous buck or boost topology.
  Replacing the catch diode with a synchronous switch
  can significantly improve overall converter efficiency
  and eliminate much of the heat that would be otherwise
  generated in the nonsynchronous catch diode.
  The advantages offered by a synchronous buck or
  boost topology can also be applied to a buck-boost
  topology, where the converter’s output voltage falls
  within its input range. In this case, a synchronous
  4-switch buck-boost converter using a single inductor
  offers the same advantages as a 2-switch synchronous
  buck or boost.
