DEMO MANUAL DC2685A
DESCRIPTION
DC2683A and DC2684A
LTC4292/LTC4291
4-Port IEEE 802.3bt PSE
Demonstration circuit DC2685A is a 4-port IEEE 802.3bt
power sourcing equipment (PSE) composed of a
DC2684A (daughter card) and DC2683A (mother-
board). The DC2685A (kit) is used for evaluation of the
LTC4292/LTC4291
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 sin-
gle power supply. A DC590 is connected to the DC2685A
for I
2
C interfacing with QuikEval™.
