This reference design utilizes the TPS23751 combination PoE PD controller and PWM controller, saving cost and size. The synchronous flyback converter provides high efficiency for PoE applications such as wireless access points and IP phones. The PoE PD can also supply up to 10W of primary power for auxiliary circuits.
