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.

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

15V, or 24V).

OUTPUT ADJUST VOLTAGE

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.
