TIDA-050023
3 类 IEEE802.3bt 就绪型反激式转换器 PoE 供电器件参考设计
TIDA-050023
概述
This design showcases a low cost, Type-3, Class 6, 51W flyback converter for powered devices through Power over Ethernet. The TPS2373-3 PD controller provides detection and classification while also powering up the LM51551-Q1 PWM controller through its advanced startup feature. This design takes in a 42V-57V PoE input and outputs a 12V rail for applications such as IP network cameras and wireless access points.
