Description

Demonstration kit DC1840B is a 12-port Type 2 power

sourcing equipment (PSE) composed of a DC1682B

daughter card and DC1680A mother board. The kit is

used for evaluation of the LTC4270B and LTC4271 PSE

chipset. Up to 12 powered devices (PDs) can be con-

nected and powered from this system using a single power

supply. A DC590B is connected to the DC1840B for I2C

interfacing with QuikEvalâ¢. This demonstration manual

provides a Quick Start Procedure, a DC1682 overview,

a DC1680 overview, schematics, and layout printouts.

Other available supporting documents for the DC1840

are the LTC4270/LTC4271 Layout Guide and the LTC4271

PSE Demo Software Users Manual.
