Description
The RP15-AW series are ultraminiature wide input voltage range power DC/DC converters in a case
half the size of industry standard 15W converters. Despite their small size, the RP15-AW converters
are fully specified devices with output currents up to 4 Amps, no minimum load, 1600VDC isolation
and low ripple/noise figures. The outputs are also fully protected against short circuits, overcurrent and
overvoltage. The RP15-AW series will find many uses in applications where board space and/or board
height is at a premium.

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 for single output
add suffix “N” for CTRL function with negative logic (0=ON, 1=OFF) and trim pin for single output
Note4: add suffix -HC for premounted Heat-sink and clips

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.
