Artesyn launches high-efficiency, eighth and quarter brick digital DC-DC converters

Artesyn Embedded Technologies has launched two new digitally-controlled dc-dc converters, the ADO300 and ADQ700, intended for use in telecom, computing and server applications.

Both converters are in standard DOSA compliant digital interface brick format and pin configuration and are available with baseplate or open frame options. Both are highly efficient and offer enhanced thermal performance and can operate between -40°C and 85°C with air cooling – meeting requirements telecom network and data centre equipment manufacturers.

Both 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. As isolated converters they are able to supply power to downstream digital dc-dc converters such as the LGA80D series from Artesyn or analogue point-of-load converters.

The ADO300 is a new generation, single output digitally-controlled dc-dc converter with standard eighth-brick outline and pin configuration. It 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 a 95.2 percent ultra-high full load efficiency with excellent thermal performance. The new 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 percent efficiency typical at 50 percent load and excellent thermal performance, together with an enhanced pre-bias start-up capability, makes it suitable for use in datacom and telecommunication applications.

Both are RoHS 6 compliant, feature input under- and overvoltage lockout, together with output overvoltage 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.
