DC/DC Buck Boost

DC/DC buck boost conversion is equivalent to a flyback converter using a single inductor instead of a transformer.

Design challenges

  • Economical, two-MOSFET design - low QG(tot) & low FOM for best efficiency
  • Step-down of voltage while stepping up current
  • D1 and D2 can be exchanged for MOSFETs for higher efficiency
