Isolated Fly-Buck Power Module for PoE Application

PMP9415

Design files

Overview

The PMP9415 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 only Power part which can provide 33V-57V input votlage and 12V 1A output power. The design features the LM5160 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 LM5160 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. 

Features
• Single 12V 1A output
• Fly-Buck converter design, primary side regulation, compact solution with TPS2378
• Wide input voltage range  of 33V to 57V
• Provide 12W supply power , 89% peak efficiency.
• LM5160 sync buck regulator, up to 65V wide Vin range, 1.5A capability
• This circuit board is tested, and the design files and test report are included.

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
