Description
The CAR1612FP series of Front-End rectifiers provide highly efficient isolated power from worldwide input mains in a
compact 1U industry standard form factor in an unprecedented power density of 19W/in
for datacom applications such as enterprise networking, mid to high-end servers, and storage equipment, where mid
to light load efficiency is of key importance given the nature of the power consumption of the end application.
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.
Input: 85Vac to 264Vac; Output: 12 Vdc @ 1600W; 3.3Vdc or 5 Vdc @ 1A
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.
