The SPM15 series is designed for applications that require Vin ranges of 9-36V or 18-75V at 15W. The SPM25 series covers applications that require Vin = 36-75V at 25W. They are 5-side-shielded, encapsulated converters, measuring 25.4 x 25.4 x 10.41 mm that offer an industry standard footprint, and incorporate the latest PWM technologies, and synchronous rectification techniques to achieve efficiency of 88%. A thermally conductive encapsulation material improves the thermal performance in applications where there is little or no airflow, and 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 – 40C to + 85C. Protection features include over-current, over-temperature and under-voltage lockout. Basic insulation provides input to output isolation of 1,600 VDC.
