Description
The RP20-A 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-A 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-A 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.

Ordering Examples
RP20-2405SA/P = 24V Input, 5V Output, Positive Logic CTRL pin and Trim pin fitted
RP20-4812DA-HC = 48V Input, 12V Output, Heat-sinꢀ fitted
Notes:
Note3: no suffix for standard part without Trim or CTRL
add suffix “P” for CTRL function with positive logic (1=ON, 0=OFF) and trim pin
add suffix “N” for CTRL function with negative logic (0=ON, 1=OFF) and trim pin
Note4: add suffix -HC for premounted Heat-sinꢀ and clips
