Product overview

Description

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 CCM converter featuring synchronous rectification with gate driver transformer.
