OUTPUT ADJUST VOLTAGE
This feature allows the user to accurately adjust the
module's output voltage set point to a specified level.
This is achieved by connecting a resistor or potentiometer
from the TRIM terminal to either the +Vout terminal (for
increased Vout) or the -Vout terminal (for decreased
Vout). The formulae below describe the trim resistor
value to obtain a Vout change of
∆
%. V
O
is output
voltage prior to adjustment (3.3V, 5V, 12V, 15V, or 24V).
Radj - up =
OVP NOTE
Special attention should be given to the peak voltage
deviation during a dynamic load step when trimming
the output above the original set point to avoid
tripping the overvoltage protection circuit. Should an
OVP condition occur, the converter will go into a
latch condition and must be externally reset before it
will return to normal operation.
