PMBus 600W DOSA Compliant, Digital 1/4 Brick DC-DC converter (web)

March 5, 2019 -- Murata has launched a series of 600W, DOSA compliant, 12V output, digital quarter-brick DC-DC converters from Murata Power Solutions. The series was designed for The DSQ, DCQ and DAQ converters support the full ‘TNV’ input range of 36 – 75V, with a typical efficiency of 96 % @ full load 48Vin.

The series is designed to support droop mode current sharing of multiple modules for increased power output with tight load sharing. I/O Isolation is 2250 VDC, with a functional insulation system and it carries the UL/CSA safety agency approvals. Options for these modules include a digital interface supporting the latest PMBus command set, parallel load sharing, positive or negative on/off logic, along with options for standard “analog” DOSA pinout and a 5pin Bus Converter pinout. Application examples include, telecommunications networking equipment, computing equipment, wireless base stations, PoE systems, MicroTCA, fan trays and test equipment.

The DSQ model includes a PMBus interface that provides a means (I2C Bus) to configure output voltage, soft start parameters, input and output over-voltage protection limits, input under-voltage lockout, current limit and thermal shutdown. Telemetry functions include output voltage and current, input voltage and temperature, as well as indications for ‘power good’ and on/off status. The heart of the module is a 32-bit processor controlling all functions and parameters. To support the PMBus, Murata Power Solutions is offering an optional evaluation board that is supported by downloadable software with a user-friendly GUI. The evaluation boards and a GUI manual are available upon request.

The DSQ modules are designed, tested and qualified according to mounting an additional heat sink for extreme temperature applications. Safety certifications include UL/EN/IEC 60950-1 and CAN/CSA-C22.2 No 60950-1 2nd edition and the parts are compliant with EN55022/CISPR22 EMC standards with minimal input filtering.

“Murata Power Solutions is proud to offer the 600W DOSA ¼ brick series to power systems architects around the world. The high reliability design and manufacturing process and advanced digital control platform with Murata’s proprietary firmware provides the power system designer the tools for the next generation, high performance systems.” said Bill Smith, Director of Product Management, Murata Power Solutions.
