STEVAL-POE005V1

Evaluation Board, PM8804 SiP, Power Over Ethernet (PoE) Interface, High Power, 12V, 8A Новинка.

High power PoE PD forward active clamp 12V up to 8A evaluation board. It allows an easy verification of a PD interface compliant with the new IEEE802.3bt standard based on PM8805 and of a DC-DC active clamp forward converter based on PM8804 controller. The PM8805 is a highly integrated device embedding two active bridges and an IEEE802.3bt compliant powered device (PD) interface. It can be successfully used in all medium to high power, 2P and /or 4P high efficiency PoE/ PoE+ applications. The PM8804 is a PWM controller that integrates all the circuitry required to design a smart and efficient 48 V converter. It features a programmable oscillator for the switching frequency, adjustable slope compensation, dual complementary low-side drivers with programmable dead time and soft start, soft turn off and a programmable current sense blanking time.
