Notes:
Note5: An external filter capacitor is required for normal operation. The capacitor should be capable of handling 1A
ripple current for 48V/24V models. RECOM suggest: Nippon chemi-con KY series, 220μF/100V, ESR 90m Ω
Note6: Simulated source impedance of 12μH. 12μH inductor in series with +Vin
Note7: The RP15-F series requires a minimum of 10% loading on the output to maintain specified regulation. Operation
under no-load condition will not damage these devices, however they may not meet all listed specification
Note8: The ON/OFF control function can be p ositive or negative logic. The pin voltage is referenced to -Vin pin

OUTPUT VOLTAGE 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 choosing 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.
