Description

The CAR2024FP series of Front-End rectifiers provide highly efficient isolated 2000 watts @ 24Vdc power from
worldwide input mains in a compact 1U industry standard form factor in an unprecedented power density of 21W/in
These rectifiers are ideal for either datacom or telecom applications such as enterprise networking, remote base
stations, 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

2

growth. The industry standard PMBus compliant I

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.
