Murata Power Solutions DSE / DAE / DCE 400W DOSA Digital PMBus Interfaces are DOSA compliant, digitally controlled DC-DC converters based on a 32-bit Arm processor. Murata DSE / DAE / DCE provides a fully regulated, digitally controlled DC output in a eighth-brick format that supports the DOSA industry standard footprint for isolated board mounted power modules. These DC/DC converters support advances in power conversion technology, including a digital interface supporting the PMBus protocol for communications to power modules. These devices support a 36-75V input range with a typical efficiency of 95.5%. DSE / DAE / DCE devices incorporate a droop load sharing option that allows connecting two or more units together in parallel for demanding applications or for providing redundancy in high-reliability applications.
