Description

Demonstration circuit 1080A is a high-power tripleoutput supply featuring the LTC4268-1. This board acts as a pre-standard high power Power-over-Ethernet (PoE) Powered Device (PD) and connects atthe RJ45 to a compatible high power Power Sourcing Equipment (PSE) device. The LTC4268-1 providesIEEE802.3af standard PoE PD interfacing. When the PD is fully powered, the PD interface switches power over to the switcher through an on-board high power MOSFET.The highly-integrated LTC4268-1, small supply utilizes an isolated flyback topology with synchronous rectification that requires no opto-isolator allowing or low-parts count. The DC1080A output supplies are 5V @ 2.4A, 11.8V @ 0.27A, and 3.3V @ 2.5A.DC1080A also demonstrates the use of an auxiliary24V wall adapter. When present, the auxiliary supply becomes the dominant supply over PoE to provide
power.
