Murata: Highly reliable encapsulated DC-DC converters for harsh environment applications with 88% efficiency
These compact, 5-side-shielded, encapsulated converters, measuring 25.4 x 25.4 x 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 and dust, vibration, or extreme temperature variations are likely to occur during normal operation.
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 -40ºC to +85ºC, 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 1,600 VDC.
