    STEVAL-POE003V1

    5V/20A, active clamp forward converter, Power Over Ethernet (PoE) - IEEE 802.3bt compliant reference design

    Parameters
    Target ApplicationAC-DC Topologies
    Core ProductPM8804, PM8805
    ECCN USEAR99
    ECCN EUNEC
    Packing TypeNot Applicable
    RoHs compliantEcopack2
    GradeIndustrial
    Package NameCARD
    Description

    This reference design represents a PoE Class 8 converter designed for high efficiency conversion over a wide load range. It is based on the PM8805 PoE-PD interface compliant with the IEEE802.3bt standard, and a DC-DC forward active clamp converter driven by the PM8804 PWM controller.The PM8805...
