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 8. 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. 3 NCF010_6200810000_A03_025Jun07 Murata Power Solutions Volant NCF010 Series Non-Isolated 10A SIP DC/DC Converters TYPICAL DERATING CURVES NCF0100100B (5Vin) Derating Curve Output Current (A) 12 10 8 0 LFM 100 LFM 200 LFM 6 4 2 0 0 20 30 40 50 60 70 80 90 Ambient Temperature (C) Figure 2.

Vr = 0.8 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 Vout Vr V 1 R1 Rt The values of Vr , R1 and Rt are as defined above. ΔV is the adjustment trim required. Examples: Vout = 1.5V Trim_Up required 8% to 1.62V Rtrim_Up 30100 0.8 100000 0.12 Rtrim_Up 100.66 k Vout = 1.5V Trim_Down required 8% to 1.38V Rtrim_Down 1.5 0.8 0.12 1 30100 100000 Rtrim_Down 45.483 k 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 NCF 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 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. The converters and materials meet UL 94V-0 flammability ratings. 13 NCF010_6200810000_B01_21/04/08 Murata Power Solutions Volant NCF010 Series Non-Isolated 10A SIP DC/DC Converters SMT Lead free Reflow profile 1.
