Murata release PMBus 600W DOSA Compliant, Digital 1/4 Brick DC-DC Converter

Date Published : 16/09/2019 Share with:

Murata has introduced a series of 600W, DOSA compliant, 12V output, digital quarter-brick DC-DC converters from Murata Power Solutions. The series was designed for high reliability applications, the heart of the module is a 32-bit ARM processor that supports the latest PMBus commands for digital control and telemetry functions. 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.

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 ARM processor controlling all functions and parameters.

The DSQ modules are designed, tested and qualified according to the industry standard IPC9592 for reliability requirements. Electrical performance is state-of-the-art starting with an efficiency rating of 96% with 600W output power @ 55°C with no heat sink, output Pre-Bias protection under all conditions, tight line & load regulation, low output ripple & noise and fast load transient response, all packaged into an industry standard DOSA quarter brick format.
All variants include a baseplate for optimal thermal performance that also provides a surface for 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.

The DSQ series DC-DC converters are suitable for a number of applications including communications & networking equipment, computing equipment, wireless base stations, PoE systems, MicroTCA, fan trays and test equipment.
