The thermal data presented is based on measurements taken at various airflows. Note that airflow is parallel to the long axis of the module as shown in Figure 1 and derating applies accordingly. TML TML Figure 1. Thermal Tests Set-Up. The temperature at either TML 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). Convection Requirements for Cooling To predict the approximate cooling needed for the module, refer to the Power Derating Curves in Figures 2-17 . 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. 3 NCA005_6200830000.B01 Murata Power Solutions Volant NCA005 Series Non-Isolated 5A SIP/SMT DC/DC Converters TYPICAL DERATING CURVES SIP/SMT VERSION NCA0051331S0 Vo=0.75V Derating Curve 6.0 Output Current (A) 5.0 4.0 0LFM 100LFM 200LFM 3.0 2.0 1.0 0.0 20 30 40 50 60 70 80 90 100 Ambient Temperature (C) Fig. 2.

If this product is built into information technology equipment, the installation must comply with the above standard. An external input fuse of less than 50 Amps (5A to 30A 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.
