STEVAL-POE005V1 (STMICROELECTRONICS)

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.
