Output Voltage Trim
Note: For setting nominal output voltage pin 8 must
be connected to pin 9.
The trim feature allows the user to adjust the output
voltage from the nominal.

production margin testing.
Output voltage can be adjusted by an external
resistor.
together the output will decrease to a low value. To
increase Vo a resistor should be connected between
pin 8 / 9 and pin 17 ( -Vin). To decrease Vo, a
resistor should be connected between pin 8 and 9
(NOR).
To increase Vo:
Radj = A x (B - Vd) / (Vd - Vo), k
Where: Vd = Desired output voltage
To reduce Vo:
Radj = C x (Vo - Vd) / (Vd - D), k
Where: Vd = Desired output voltage
Notes:

Parallel Operation
Paralleling of two converters is possible by direct
connection of the output voltage terminal pins. The
load regulation characteristic is designed to facilitate
current sharing (typically ± 20%).

Model
output power from the converter must not
exceed its maximum rating. This is determined
by measuring the output voltage on the output
pins, and multiplying it by the output current.
The trim feature allows the generation of
additional standard voltages such as ±15 V from
the ±12 V model.

Output Current Limiting
When the output is overloaded above the maximum
output current rating, the voltage will start to reduce
to maintain the output power to a safe level. In a
condition of high overload or short-circuit where the
output voltage is pulled below approximately 30% of
Vo.Nom, the unit will enter a ‘Hiccup’ mode of
operation. Under this condition the unit will attempt
to restart, approximately every 100 ms until the
overload has cleared.

Remote Control Feature
The remote control pin functions as a normal soft
shutdown. It is referenced to the –Vin pin. With
positive logic, when the remote control pin is pulled
low, the output is turned off and the unit goes into a
very low input power mode.
An open collector switch is recommended to control
the voltage between the remote control pin and -Vin
pin of the converter. The remote control pin is pulled
up internally, so no external voltage source is
required.

the remote control pin is not used, it can be left
floating.
