300W Eighth- and 700W Quarter-Brick DOSA Digital DC-DCs
Artesyn Embedded Technologies launched two new digitally-controlled dc-dc converters, the ADO300 and ADQ700, suited to 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. Their high efficiency and superior thermal performance enables operation between -40 and 85 degrees C with air cooling - now demanded by telecom network and data center equipment manufacturers.
Both 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. They are designed for use as isolated converters supplying power to downstream 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. This converter can handle an input range of 36- to 75-Vdc, delivers up to 26A output current at 11.7Vdc output voltage with 95.2 percent full load efficiency. 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 new generation, 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-Vdc and delivers up to 58A output current at 12Vdc output voltage. The 96 percent efficiency typical at 50 percent load, together with an enhanced pre-bias start-up capability, makes it a good 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.
