Artesyn Embedded Technologies has launched two new digitally controlled DC/DC converters, the ADO300 and ADO700, ideally suited to telecom, computing and server applications. Both converters are in standard DOSA- compliant digital interface brick format and pin configuration, and they are available with baseplate or open frame options. Their high efficiency and good thermal performance enables operation between –40° C and +85° C with air cooling—now demanded by telecom network and data center 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 ideal as isolated converters supplying power to downstream digital DC/DC converters, such as Artesyn’s LGA80D series or analog point-of-load converters.

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 to 75 V, delivers up to 26 A output current at 11.7 V output voltage, and features an outstanding 95.2% ultra-high, full- load efficiency with excellent thermal performance. 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.

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 to 60 V and delivers up to 58 A output current at 12 V output voltage. The ultra-high 96% efficiency rate typical at 50% load and excellent thermal performance, together with an enhanced pre-bias start-up capability, make it ideal for use in datacom and telecommunication applications.

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