This reference design implements a Power over Ethernet (PoE) Power Device (PD) flyback converter with 12-V and 2.1-A output. TPS23731 PD and PWM controller provides all necessary functions to implement the PoE PD control and PWM control for the flyback converter. TPS23731 uses primary side regulation (PSR) that eliminates the need for optocoupler feedback.
