Despite their small size, the RP20-A converters are fully specified devices with output currents up to 4.5 Amps, up to 91% efficiency, no minimum load, Single and Dual 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-A series will find many uses in applications where board space and/or Output board height is at a premium or in battery-powered systems where standby current is important.
