STEVAL-TSP004V2:PoE 5 V - 4 A PD converter based on the PM8803 IEEE802.3at compliant synchronous flyback controller

The STEVAL-TSP004V2 is a reference design for a PoE+, high-efficiency, 5 V - 4 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-TSP004V2 reference design is based on an isolated flyback topology CCM converter featuring synchronous rectification with gate driver transformer.
