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. This can be
used to accommodate a different requirement or
to do production margin testing.
Output voltage can be adjusted by an external
resistor. If pin 8 and pin 9 are not connected
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
Vo = Nominal output voltage.
To
reduce
Vo:
Radj = C x (Vo - Vd) / (Vd - D) k
Where: Vd = Desired output voltage
Vo = Nominal output voltage.

Notes:
1. When the output voltage is trimmed up, the
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.
2. The trim feature allows the generation of
additional standard voltages such as 2.5V
from 3.3V model, 15V from 12V model and 6V
or 8V from the 7V 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 100ms until the overload has
cleared.
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%).
Thermal Considerations
The converter is designed for natural or forced
convection cooling. The output power of the
converter is limited by the maximum case
temperature (Tc). To ensure reliable long term
operation of the converters, and to comply with
safety agency requirements, Power-One limits
maximum allowable case temperature (Tc) to
110°C (see Mechanical Drawings).
