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.

RP20-4812DAW/N = 48V 4:1 input, ±12V Output, negative logic with CTRL pin and Com pin fitted
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), 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

Note6: Trimming allows the user to increase or decrease the output voltage set point of the module. This is accomplished by connecting
an external resistor between the Trim pin and either +Vout pin or -Vout pin. Please refer to next page
Note7: The ON/OFF control function can be positive or negative logic. The pin voltage is referenced to -Vin pin. If no suffix is specified,
the control pin will be omitted

External Output Trimming
Output Voltage Trimming
Single output Powerline converters offer the feature of trimming the output voltage over a certain range around the nominal value by using external
trim resistors. No general equation can be given for calculating the trim resistors, but the following trimtables give typical values for chosing these
trimming resistors. If voltages between the given trim points are required, extrapolate between the two nearest given values to work out the resistor
required or use a variable resistor to set the output voltage. Output can be externally trimmed by using the method shown below.
