Despite their small size, the RP20-AW converters are fully specified devices with output currents up to 4.5 Amps, up to 90% 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-AW series will find many uses in applications where board space and/ Output or board height is at a premium or in battery-powered systems where standby current is important.
