STEVAL-TSP009V2、3.3V/6A 同步反激转换器、以太网供电 (PoE) - 符合 IEEE 802.3at 的参考设计

newrudeman 发布

STEVAL-TSP009V2，基于 PM8803 PoE 控制器的 PoE+ 高效 3.3V/6A 反激式转换器参考设计。 PM8803 是一款高度集成的设备，嵌入了符合 IEEE802.3at 标准的受电设备 (PD) 接口以及 PWM 控制器并支持辅助电源。 STEVAL-TSP009V2 参考设计基于隔离式反激式 CCM 转换器，具有带栅极驱动器变压器的同步整流功能

说明

STEVAL-TSP009V2, Reference Design for a PoE+, high-efficiency, 3.3V/6A flyback converter based on the PM8803 PoE controller. The PM8803 is a highly integrated device embedding an IEEE802.3at-compliant powered device (PD) interface together with a PWM controller and support for auxiliary sources. The STEVAL-TSP009V2 reference design is based on an isolated flyback CCM converter featuring synchronous rectification with gate driver transformer
