DC-DC Converter Modules from Murata
DC-to-DC converter modules.
Mansfield, MA — Murata has introduced the SPM series of low power isolated DC-DC modules designed specifically for use in electronic equipment that will be subject to harsh environments such as outdoor communications, applications with little or no forced air cooling, smart grid and industrial process control equipment. The SPM15 series modules are designed for applications that require Vin ranges of 9-36V or 18-75V at 15W. The SPM25 series covers applications that require Vin of 36-75V at 25W.

These compact, 5-sided shielded, 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 one of the industry's highest energy efficiency ratings of 88 percent. A thermally conductive encapsulation material greatly improves the thermal performance in applications where there is little or no airflow, providing a stable platform for environments where dirt and dust, vibration or extreme temperature variations are likely to occur during normal operation.

The SPM15 and SPM25 modules 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. The operating temperature range is from -40 to +85°C, and the modules are designed for use in the most demanding environments.

Protection features include over-current, over-temperature and under-voltage lockout. Basic insulation provides input-to-output isolation of 1,600VDC.

The modules are suitable for use in high-reliability industrial process control, smart grid and transportation infrastructure equipment.
