Demonstration circuit 2685B is a 4-port IEEE 802.3bt power sourcing equipment (PSE) composed of a DC2684A-B (daughter card) and DC2683A (motherboard). The DC2685B (kit) is used for evaluation of the LTC4291-1/LTC4292 PSE chipset. Up to four IEEE 802.3af, IEEE 802.3at, or IEEE 802.3bt powered devices (PDs) can be connected and powered from this system using a single power supply. A DC590 is connected to the DC2685B for I2C interfacing with QuikEval™.
This demonstration manual provides a quick start procedure, a DC2684A-B daughter card overview, a DC2683A mother board overview, schematics, and layout printouts.
