Description

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%.

Features
  • Generate two outputs with a single device and a single power stage.
  • The TPS562209 comes in a tiny SOT23 package.
  • DCAP2 control reduces output capacitance and eliminates extra compensation components.
  • Auxilliary output is left floating and can be referenced to any node, or used as a negative output, if required.
  • Good efficiency, over 92%.
