95% Efficient 300W Eighth-brick Isolated DC-DCs with PMBus

Artesyn Embedded Technologies has announced two new models in its ADO300 series 300W eighth-brick converters, providing single 3.3V or 5V outputs.

The ADO300 is a new generation digitally-controlled dc-dc converter with standard eighth-brick outline and pin configuration. It can handle an input range of 36- to 75-Vdc, delivers up to 60A output current at 3.3V or up to 60A output current at 5V output voltage.

The ADO300 converter series features an outstanding 95.2% full load efficiency with excellent thermal performance. It has an enhanced pre-bias start-up capability and for high current applications two converters can be connected in parallel, automatically using droop current sharing.

Designed for telecom, computing and server applications, the ADO300 series is available with baseplate or open frame options. High efficiency and superior thermal performance enables operation between -40 degrees Celsius and 85 degrees Celsius with air cooling – now demanded by telecom network and data center equipment manufacturers.

The new converters provide flexible and comprehensive digital communication via the PMBus® command protocol with control and monitoring functions for voltage, current, temperature and the reporting of fault conditions.
