The RP15-A series are ultraminiature power DC/DC converters in a case half the size of industry
standard 15W converters. Despite their small size, the RP15-A 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-A
series will find many uses in applications where board space and/or board height is at a premium.

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.
