Features Description ● ● ● ● ● ● ● ● ● ● ● POWERLINE Ultraminiature 25.4 x25.4x9.9mm Package 20 Watts Output Power Single or Dual Outputs Wide 2:1 Input Voltage Range 1.6kVDC Isolation Fixed Operating Frequency Six-Sided Continuous Shield Industry Standard Pinout Remote On/Off and Trim pins Undervoltage Lockout Efficiency to 90% DC/DC-Converter with 3 year Warranty 20 Watt 1” x 1” Single & Dual Output The RP20-SA series are ultraminiature 2:1 input voltage range power DC/DC converters in a case half the size of industry standard 20W converters. Despite their small size, the RP20-SA converters are fully specified devices with output currents up to 4.5 Amps, up to 91% efficiency, no minimum load, 1600VDC isolation, a built-in Class A EMC filter and low ripple/noise figures. The outputs are also fully protected against short circuits, overcurrent and overvoltage. The no load input current is particularly low (only 4mA/6mA). The RP20-SA series will find many uses in applications where board space and/or board height is at a premium or in battery-powered systems where standby current is important.
