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.
Class 4- Dual PoE+ (Power Over Ethernet)
PMP6998.1: The PMP6998 reference design is an isolated Flyback which uses an LM5072 and is intended for Power over Ethernet (PoE) applications. It can generate isolated outputs of 3.3 Volts at 3.3 Amps and 5 Volts at 2 Amps from an input of 38 to 60 Volts DC. An auxiliary input supply of 12 Volts may also be used with this design.
High-Efficiency Isolated Flyback Converter Reference Design for PoE Application
PMP9446: PMP9446 is an Isolated Flyback Converter using the LM5022 controller IC. The design accepts an input voltage of 10Vin to 15Vin (12Vin Nominal) and provides an output of 54Vout capable of supplying 0.75A of continuous current to the load. The design was built on the PMP7899 PCB, which was modified to the PMP9446 design configuration and requirements.
Class 4- Dual PoE+ (Power Over Ethernet)
PMP6998.2: The PMP6998 reference design is an isolated Flyback which uses an LM5072 and is intended for Power over Ethernet (PoE) applications. It can generate isolated outputs of 3.3 Volts at 3.3 Amps and 5 Volts at 2 Amps from an input of 38 to 60 Volts DC. An auxiliary input supply of 12 Volts may also be used with this design.
1.25W Isolated Flyback Converter for Analog/Digital Power
PMP7902: PMP7902 is an Isolated Flyback converter utilizing the LM5001 non-synchronous current-mode regulator I.C. The design accepts an input voltage of 4.5V to 5.5V and provides an isolated 5V output capable of supplying 0.25A of current to the load. The design uses an off-the-shelf VERSAPAC transformer, providing 500V of operational isolation between primary and secondary. A precision shunt regulator provides a tight control of the output voltage using an optocoupler to cross the isolation barrier.
