Features Description ● ● ● ● ● ● ● ● Ultraminiature Open Frame SMD 15 Watts Output Power 2:1 Input Voltage Range Single Outputs 2.25kVDC Isolation Fixed Operating Frequency Optional Remote On/Off and Trim pins Efficiency to 88% POWERLINE DC/DC-Converter with 3 year Warranty 15 Watt Single Output Open Frame SMD The RP15-SOF series are SMD open frame ultraminiature power DC/DC converters in a case half the size of industry standard 15W converters. The converters use solder ball pins to enable SMD mounting and can be reflow soldered. Despite their small size, these converters are fully specified devices with output currents up to 3.5 Amps, no minimum load, 2250VDC isolation and low ripple/noise figures. The outputs are also fully protected against short circuits, overcurrent and overvoltage. The RP15-SOF series will find many uses in telecommunications and other demanding applications where cost, board space or board height is at a premium.
