2:1 input voltage range Features 1.6kVDC isolation DC/DC Converter UL certified Efficiency up to 89% Regulated Six-sided continuous shield Converter No minimum load required RP15-A Description 15 Watt The RP15-A series are ultraminiature power DC/DC converters in a case half the size of industry 1 x 1 standard 15W converters. Despite their small size, the RP15-A converters are fully specified devices with output currents up to 4 Amps, no minimum load, 1600VDC isolation and low ripple/noise figures. Single and Dual The outputs are also fully protected against short circuits, overcurrent and overvoltage. The RP15-A series will find many uses in applications where board space and/or board height is at a premium. Output Selection Guide (1) (1) Part Number Input Output Output Input Efficiency Max.
