Datasheets & Reference Designs

Reference Designs

  • Class 1 Non-isolated Buck Converter (5V/560mA) for PoE PD Applications Reference Design
    PMP9676: 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.
  • Isolated Fly-Buck Power Module for PoE Application Reference Design
    PMP10572: The PMP10572 reference design is an single output isolated Fly-Buck power supply for PoE application. It takes 48V nominal input and provides 12V 1A output. The board is designed with TPS2378(PD controller) to provide 40V-57V input votlage and 12V 1SA output power. The design features the LM5160A synchronous buck converter configured as a Fly-Buck regulator. With the benefit of primary side regulation, the supply has the outputs regulated without the opto-coupler or additional transformer winding. The LM5160A has a wide Vin range of 4.5V to 65V and 1.5A output current capability with integrated switch FETs. The input voltage to the reference board can be loosely regulated with a range of 40V to 57V.
  • UPOE High-Efficiency Flyback Converter (19V/2.3A) for Forced 4-Pair PoE PD Apps Reference Design
    TIDA-00539: TIDA-00539 uses two TPS2378 PD controllers for a forced 4-pair UPOE solution to 51W non-standard PoE PD applications. It incorportates the UCC2897A controller in a high-efficiency, great transient response (driven) synch flyback converter capble of 19V at 2.3A.
