Digital DC/DC converters suitable for telecom applications

Their high efficiency and superior thermal performance enables operation between -40 and 85°C with air cooling - now demanded by telecom network and data centre equipment manufacturers.

Both 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. They are useful as isolated converters supplying power to downstream digital DC/DC converters such as Artesyn’s LGA80D series or analogue point-of-load converters.

ADO300: 300W eighth-brick converter
The ADO300 is a single output digitally-controlled DC/DC converter with standard eighth-brick outline and pin configuration. This converter can handle an input range of 36-75V, delivers up to 26A output current at 11.7V output voltage and features 95.2% high full load efficiency. The ADO300 converter 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.

ADQ700: 700 W quarter-brick converter
The ADQ700 is a single output DC/DC converter with standard quarter-brick outline and pin configuration. The DC/DC converter can handle an input of 40-60V and delivers up to 58A output current at 12V output voltage. The 96% efficiency typical at 50% load, together with an enhanced pre-bias start-up capability, makes it a useful choice for use in datacom and telecommunication applications.

The ADO300 and ADQ700 are RoHS 6 compliant, feature input under- and overvoltage lockout, together with output overvoltage and current protection and full overtemperature protection. These DC/DC bricks extend Artesyn’s growing portfolio of digital DC/DC converters, which also includes the 500W quarter-brick ADQ500 series.
