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

Notes:
Note5: Simulated source impedance of 12µH. 12µH inductor in series with +Vin.
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
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
Some single/dual 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.
