Murata Power Solutions DSE / DAE / DCE DOSA Digital PMBus Interfaces

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 an 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 36V to 75V input range with a typical efficiency of 95.5%. DSE / DAE / DCE devices incorporate a droop load-sharing option that allows the connection of two or more units together in parallel for demanding applications or for providing redundancy in high-reliability applications.
