STEVAL-TSP004V2
PoE 5 V - 4 A PD converter based on the PM8803 IEEE802.3at
compliant synchronous flyback controller
Data brief
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 topology CCM
converter featuring synchronous rectification with
gate driver transformer.
Features
