Encapsulated dc/dc converters offer 88% efficiency

A new family of isolated dc/dc modules, designed specifically for harsh environments, has been unveiled by Murata.
The SPM15 devices are designed for applications that require Vin ranges of 9 to 36V or 18 to 75V at 15W, while the SPM25 series covers applications that require Vin = 36 to 75V at 25W.
The five sided, encapsulated converters, measuring 25.4 x 25.4 x 10.41mm, offer an industry standard footprint, incorporate the latest PWM technologies, automated assembly processes and synchronous rectification techniques to achieve a high energy efficiency rating of 88%.
Murata says the inclusion of a thermally conductive encapsulation material greatly improves the thermal performance in applications where there is little or no airflow, and provides a stable platform for environments where dirt, dust, vibration or extreme temperature variations are likely to occur during normal operation.
The SPM15 and SPM25 families provide single output voltages of 3.3, 5 or 12VDC. In addition, the SPM15 has a 15VDC output option. The SPM15 is available with two wide input range options of 9 to 36VDC or 18 to 75VDC.
The SPM25 accommodates an input range around a 48VDC nominal from 36 to 75VDC.
