12V Input 3W Dual 5V Output Synchronous Buck Converter
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%.
