This supply uses the TPS562209 buck converter to generate a 5V/0.5A regulated output and an auxilliary 5V/0.2A unregulated output. A two winding coupled inductor is used to generate the auxilliary output. The auxilliary output is left floating, and could be used as a -5V output or as a second +5V output. This simple design results in an efficient, yet low cost solution for a dual output system. The peak efficiency is over 92%.
