Description
The CAR2512TE Front-End provides highly efficient isolated power from worldwide input mains in a compact 1U
industry standard form factor in an unprecedented power density of 25W/in
3
. Ideal for applications where mid to light
load efficiency is of key importance. This front-end is complemented by the CAR2512DC dc/dc converter designed to
convert 48/60Vdc power of telecom central offices. This plug and play approach offers rapid system reconfiguration
by simply replacing the power supply.
The high-density, front-to-back airflow is designed for minimal space utilization and is highly expandable for future
growth. The industry standard PMBus compliant I
2
C communications buss offers a full range of control and
monitoring capabilities. The SMBAlert signal pin alerts customers automatically of any state change within the power
supply.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only, functional
operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet.
Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.
