产品概述
描述
This document focuses on a reference design for a simple, low cost 3.3 V 3 A flyback converter based on the PM8800A device. The PM8800A is a highly integrated device embedding an IEEE 802.3af compliant “Powered Device” (PD) interface together with a PWM controller.
It can be successfully used in all low power, low cost PoE applications.
