TORQUE, 8 IN/LBS 2.40 [61.0] MAX MECHANICAL 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. 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%) ) kΩ 1.225 Δ% Δ% Radj - down = (100 - 2) kΩ Δ% 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.
