1 / 7 page April 2015 DocID027732 Rev 1 1/7 For further information contact your local STMicroelectronics sales office www.st.com STEVAL-TSP009V2 PoE 3.3 V - 6 A PD converter based on the PM8803 IEEE802.3at-compliant, synchronous flyback controller Data brief Features IEEE 802.3at compliant PD interface Works with power supplied from Ethernet LAN cables or from local auxiliary sources Line input voltage range: 40 VDC to 60 VDC Output voltage: 3.35 VDC ± 5% Output current: 6 A Peak-to-peak output ripple: < 25 mV Efficiency DC-DC full-load: > 90% Overall peak efficiency: > 87% Transient response ΔVOUTPK-PK to 50% load step: < 250 mV ΔV in load line case: < 0.5% RoHs compliant 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. |
