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. Figure 1. Thermal Tests Set-Up. The temperature at either location should not exceed 110°C. Over-temperature shutdown is evaluated at these locations. 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 NFA020_6200760000_B04_21/04/08 Murata Power Solutions Non-Isolated 20A SIP/SMT DC/DC Converters VOLANT NFA020 Series TYPICAL DERATING CURVES SIP/SMT VERSION NFA020 Derating Curve V1.0 Vout=0.75V NFA020SMT SMT Derating Curve Vout=0.75V Output Current (A) 25 20 15 0LFM 100LFM 200LFM 300LFM 400LFM 10 5 0 30 40 50 60 70 Ambient Temperature(oC) 80 90 Fig. 2.

NFA Series can also be programmed by applying a voltage between the TRIM and GND pins (Figure below). The following equation can be used to determine the value of Vtrim needed to obtain a desired output voltage Vo: For example, to program the output voltage of NFA Series module to 3.3 Vdc, Vtrim is calculated as follows: Circuit Configuration for programming Output voltage using external voltage source Table 1 provides Rtrim values for some common output voltages, whileTable 2 provides values of the external voltage source, Vtrim for the same common output voltages. By using a 1% tolerance trim resistor, set point tolerance of ±2% is achieved as specified in the electrical specification. 22 NFA016_6200890000_B01_21/04/08 Murata Power Solutions Non-Isolated 20A SIP/SMT DC/DC Converters VOLANT NFA020 Series Remote Sense: All Murata Power Solutions Technologies SMT/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. Voltage Sequencing: NFA series power modules offer the ability to precisely sequence output voltage rise. The sequence feature limits the output voltage to that presented at the Sequence pin. For example, if the sequence pin is connected to a variable voltage source, and the converter is enabled, output voltage will track the voltage applied to the sequence pin, to a maximum of the programmed output voltage. If this feature is not required, the sequence pin should remain unconnected. In practice, the Sequence pin of a lower voltage converter may be connected to a higher voltage source to ensure the lower voltage does not exceed the higher voltage during power on and power off. If multiple NFA series converters are used, all Sequence pins may be connected to the same higher voltage. In this way, all voltage rails will rise at the same rate, and cease to rise at their respective programmed output voltages. SMT Lead free Reflow profile 1.

If this product is built into information technology equipment, the installation must comply with the above standard. An external input fuse (no more 20 A 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.
