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 brass; lead finish is matte tin (100-300 micro-inches) over a
nickel barrier layer (5-40 micro-inches).”

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
Δ%. VO is output voltage prior to adjustment (3.3V, 5V, 12V,
15V, or 24V).
( ) Radj - up = Vo(100 + Δ%) _ (100 + 2Δ%) Ω
1.225Δ%
Δ%
( ) Radj - down = 100Δ-%2 Ω
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.
