Shock & vibration: Meets IPC 9592 Class II standards
Applications
12Vdc distributed power architectures
Datacom and Telecom applications
Mid to high-end Servers
Routers/Switches
Broadband Switches
ATE Equipment
Description
The CAR2012TE Front-End provides highly efficient isolated power from worldwide input mains in a compact 1U
industry standard form factor. This power supply is ideal for applications where mid to light load efficiency is of key
importance in order to reduce system power consumption during ‘typical’ operational conditions.
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 automatically alerts customers of any state change within the power
supply.

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.
