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.

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.
OUTPUT ADJUST VOLTAGE
OVP NOTE
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
%. VO is output
voltage prior to adjustment (3.3V, 5V, 12V, 15V, or 24V).
