From Murata: 400 Watt 1/8th Brick DC-DC converters support PMBus protocol for communication
Murata announces the introduction of its DSE Series, a fully isolated, 12Vout, 400W eighth brick DC-DC converter with a DOSA compliant digital interface to support the PMBus standard for communication and control. The Series, which also includes DAE and DCE products, has a droop load sharing option for paralleling up to three modules in some of the most power demanding applications. Further, the series meets the international TNV standard for Input Voltage with a 36-75Vin range and provides 2250Vdc isolation for use in Power over Ethernet (PoE) applications.
The DSE series offers advanced power conversion technology, including a 32bit ARM processor that controls critical conversion functions and delivers a digital interface for use in the end system application. The PMBus digital interface can be used to customize the modules’ configuration for specific functions and presents system engineers with critical telemetry information. Multiple pin configurations are available, as the DSE provides a DOSA standard digital eighth brick pinout with sense, trim, and PMBus. The DAE provides a DOSA analog eighth brick pinout with sense and trim (no PMBus). The DCE is a DOSA analog eighth brick in the traditional 5-pin package. Target applications include telecommunications, networking, wireless, pre-amplifiers, industrial, and test equipment.
“We have seen significant demand for higher power isolated dc-dc converters with small footprints, high efficiencies, and intelligent digital control and communications for leading-edge infrastructure equipment. By leverage Murata’s proprietary design techniques for advanced electrical, thermal, and mechanical performance, the DSE series integrates features never before attained in a modular dc-dc converter,” said Bill Smith, Director – Product Line Management, Murata Power Solutions.
