OUTPUT VOLTAGE ADJUST
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
%.
Radj - up =
(
Vo(100 +
%) - (100 + 2%) ) k
1.225
%
Radj - down =
(100 - 2) k
%
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.
NOTES:
All dimensions are in inches (millimeters).
PIN PLACEMENT TOLERANCE: ± 0.005"
MECHANICAL TOLERANCE: ± 0.015"
Marked with: specific modeL ordered, date code, job
code.
MATERIAL: Units are encapsulated in a low thermal
resistance molding compound which has excellent
chemical resistance and electrical properties in high
humidity environments and over a wide operating
temperature range. The encapsulant and outer shell of
the unit have UL94V-0 ratings. Lead material is solder
plated to allow ease of solderability.
