Description

This converter is used for Class 1 PoE PD applications where isolation is not required.  The TPS2378 PD controller plus LM5006 buck converter provide 5V/560mA with good efficieny in a small size.  The LM5006 can be configured with a diode rectifier for lowest cost or a synchronous FET rectifier for improved efficiency.

Features
  • Non-isolated 5V/560mA output
  • Diode rectifier for lowest cost
  • Synchronous rectifier for improved efficiency
  • Small size
  • Test report included
