Features Description ● ● ● ● ● ● ● ● Ultraminiature Open Frame SMD 15 Watts Output Power 4:1 Input Voltage Range Single Output 2.25kVDC Isolation Fixed Operating Frequency Optional Remote On/Off and Trim pins Efficiency to 87% The RP15-SOFW 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, the RP15-SOFW converters are fully specified devices with output currents up to 4 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-S0FW series will find many uses in telecommunications and other demanding applications where price, board space or board height is at a premium.
