Description
The RP20-AW series are ultraminiature wide input voltage range power DC/DC converters in a case
half the size of industry standard 20W converters. 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,
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/
or board height is at a premium or in battery-powered systems where standby current is important.

Notes:
Note3: standard part is without suffixes CTRL & Trim pin aren’t fitted
add suffix “P” for CTRL function with positive logic (1=ON, 0=OFF), including trim pin
add suffix “N” for CTRL function with negative logic (0=ON, 1=OFF), including trim pin
Note4: add suffix -HC for premounted Heat-sink and clips
Notes:
Note1: Values at nominal input voltage and full load
Note2: Test by minimum Vin and constant resistor load.
