3 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 1 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 to Figure. 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 and Q-pin as shown in Figure 1. 3 NCF0_00000_A03_05Jun07

12 Typical Output Noise and Ripple Output Voltage Set point adjustment. The following relationship establish the calculation of external resistors: Trim-Up For trim_up an external resistor is connected between the TRIM and Ground Pin. Rtrim_Up Vr R1 V Rt Where, Rt = internal buffer resistor. For calculation choose value as per table below: Vo, set (Volts) Rt (KΩ) NCF0_00000_A03_05Jun07

13 R1 = 30.1 KΩ Murata Power Solutions ΔV = Change in adjustment voltage required ( example % of Volts = 0.1). Vr = 0. 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 % to 1.V Rtrim_Up Rtrim_Up 0. k Vout = 1.5V Trim_Down required % to 1.3V Rtrim_Down Rtrim_Down 5.3 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 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- requirements. The converters and materials meet UL 9V-0 flammability ratings. 13 NCF0_00000_B01_1/0/0
