45 W USB-PD Ethernet Power Flyback Converter

45 W USB-PD Power over Ethernet Flyback Converter

 
Overview
Design compatible isolated 45 W USB-PD, Power over Ethernet input voltage range compatible constant voltage supply. When used together with the NCP1096GEVB IEEE 802.3bt-compatible demo board, Power over Ethernet to USB PD applications in smart building designs can be implemented. Fixed frequency flyback design using ON Semiconductor NCP12700 PWM controller, NCP4306 synchronous rectifier controller, FDMS86255 primary side MOSFET and FDMS86202 synchronous MOSFET, and FUSB3307 USB-PD controller. This design document provides circuit schematic details, PCB and BOM for 45 W Power over Ethernet from Ethernet to USB-PD compatible power stage.
