The SPMxx series of encapsulated DC-DC converters are highly reliable and designed for harsh environment applications with 88% efficiency 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 was designed for applications that require Vin ranges of 9-36V or 18-75V @ 15W. The SPM25 series covers
applications that require Vin = 36-75V @ 25W.
The SPM15 & SPM25 series provides single output voltages of 3.3, 5 or 12 VDC. In addition, the SPM15 has a 15 VDC output option. The SPM15 is available with two wide input range options of 9 – 36 VDC or 18 – 75 VDC. The SPM25 accommodates an input range around a 48 VDC nominal from 36 – 75 VDC. The operating temperature range is from – 40 degrees C to + 85 degrees C, designed for use in the most demanding environments.
These compact, 5-sided shielded, encapsulated converters, measuring 1” (25.4) x 1” (25.4) x 0.41” (10.41) mm 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%. A thermally conductive encapsulation material greatly improves the thermal performance in applications where there is little or no airflow, provides a stable platform for
environments where dirt & dust, vibration or extreme temperature variations are likely to occur during normal operation.
Protection features include over-current, over-temperature and under-voltage lockout. Basic insulation provides input to output isolation of 1,600 VDC.
The SPM series provides systems design engineers with a contemporary solution for the most demanding, high reliability applications. The SPMxx series can be used as a means to address the growing requirements for dc/dc converters designed for the most sever commercial applications.
