STEVAL-TSP009V2 Datasheet, PDF (1/7 Pages) STMicroelectronics – IEEE 802.3at compliant PD interface

STEVAL-TSP009V2
PoE 3.3 V - 6 A PD converter based on the PM8803
IEEE802.3at-compliant, synchronous flyback controller
Data brief
Description
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.
