regulation. Operation under no-load condition will not damage these devices, however they
may not meet all listed specification.
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.
