onsemi PoE-PD Module with VAUX Evaluation Board DC-DC Converter for NCP1083DEG for PoE-PD Module with VAUX

The NCP1083QBCEVB implements a PoE module DC/DC converter that converts the higher voltage one the Ethernet cable to a lower voltage (12V) with power levels up to 30W. Detection, classification and power up sequence is implemented according to IEEE802.3at (D4). The board also supports getting its power from and auxiliary input, in case PoE network is not available. Auxiliary input voltage may be as low as 9V. The isolated flyback DC/DC converter design is optimized to support a very wide input voltage range (9V to 57) without compromising the overall efficiency.
