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.

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 ∆%. VO is output

voltage prior to adjustment (3.3V, 5V, 12V, 15V, or 24V).

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.
