Reference Design for a PoE 3.3 V - 6 A PD converter based on the PM8803 IEEE802.3at-compliant, synchronous flyback controller
The STEVAL-TSP009V2 is a reference design for a PoE , high-efficiency, 3.3 V - 6 A 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 topology CCM converter featuring synchronous rectification with gate driver transformer.
