Description
3
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.

Notes:
Note3: standard part is without suffix “P” or “N” = without CTRL & Trim function
Trim function is only available for single output with /P or /N suffix
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-sink with clamps
Ordering Examples
RP20-2405SA/P = 24V input, 5V output, single, positive Logic CTRL pin
RP20-4805DA-HC = 48V input, 5V output, dual, without CTRL pin, Heat-sink premounted
