Thermal Considerations
The power module operates in a variety of thermal environments; however, sufficient cooling
should be provided to help ensure reliable operation of the unit. Heat is removed by
conduction, convection, and radiation to the surrounding environment. The thermal data
presented is based on measurements taken in a set-up as shown in fig 1. when the airflow is
parallel to the long axis of the module. The de-rating applies accordingly.
The temperature at either location should not exceed 110 °C. The output power of the module
should not exceed the rated power for the module (VO, set x IO, max).
Figure 1: Thermal Measurement Setup
Convection Requirements for Cooling
To predict the approximate cooling needed for the module, refer to the Power Derating Curve in
Figure 2 to Figure 9.
These derating curve are approximations of the ambient temperature and airflow required to keep the
power module temperature below it's maximum rating. Once the module is assembled in the actual
system, the module's temperature should be verified.
Proper cooling can be verified by measuring the power module's temperature at Q1-pin 6 and Q2-pin
6 as shown in Figure 1.

Output Voltage Set point adjustment.
The following relationship establish the calculation of external resistors for the NEF series:
Trim-Up
For trim_Up an external resistor is connected between the TRIM and Ground Pin.
Rtrim − up = (
R1 × 0.7
) − Rt (KΩ )
Vo − Vo , nom
Where,
Rt = 1 KΩ
R1 = 15 KΩ
Vo,nom is the nominal output voltage
Vo is the desired output voltage
Trim_Down
For trim down an external resistor is to be connected between TRIM and Vout pins of the module.
The value of Rtrim_Down is calculated from the following relationship.
Rtrim − down =
R1 × (Vo − 0.7)
− Rt (KΩ)
Vo , nom − Vo
The values of R1 , Rt , Vo,num , Vo are as defined above.
Examples:
Vout = 1.5V Trim_Up required 8% to 1.62V
Vo – Vo,nom = 1.62 – 1.5 = 0.12V
Rtrim − up =
15 × 0.7
− 1 = 86.5 (KΩ)
0.12
Vout = 1.5V Trim_Down required 8% to 1.38V
Vo,nom - Vo = 1.5 – 1.38 = 0.12V
Rtrim − down =
15 × (1.38 − 0.7)
− 1 = 84 (KΩ)

Remote Sense:
All Murata Power Solutions SIP power modules offer an option for remote sense. The remote sense
compensates for any distribution drops to accurately control voltage at the point of load. The voltage between
the sense pin to Vout pin should not exceed 0.5V.

Safety Considerations
The NEA/NEF series of converters are certified to IEC/EN/CSA/UL 60950. If this product is built into information
technology equipment, the installation must comply with the above standard. An external input fuse (no more than 20
Amps, recommended) must be used to meet the above requirements. The output of the converter [Vo(+)/Vo(-)] is
considered to remain within SELV limits when the input to the converter meets SELV or TNV-2 requirements.
The converters and materials meet UL 94V-0 flammability ratings.
