An input line fuse must always be used. This power SIP can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow fuse with a maximum rating of 10 A (see Safety Considerations section). To aid in the proper fuse selection for the given application, information on inrush energy and maximum dc input current is provided. Refer to the fuse manufacturer’s data for further information.

Lineage Power 7 Data Sheet October 14, 2009 Test Configurations NH020-Series Power SIPs: 5 Vdc Input; 1.5 Vdc to 3.3 Vdc Output; 20 W Design Considerations Input Source Impedance The power SIP should be connected to a low ac- impedance input source. Highly inductive source impedances can affect the stability of the SIP. Adding external capacitance close to the input pins of the SIP can reduce the ac impedance and ensure system stability. The minimum recommended input capacitance (C1) is a 100 µF electrolytic capacitor (see Figures 17 and 19). T O O SC ILLO SC O PE L VI ( + ) 500 nH C S 220 µ F BAT T ER Y ESR < 0.1 • @ 20 °C , 100 k H z V I ( –) Note: Measure input reflected ripple current with a simulated source inductance (LTEST) of 500nH. Capacitor CS offsets possible battery impedance. Measure current as shown above. Figure 14. Input Reflected Ripple Current Test Setup. Figure 17. Setup with External Capacitor to Reduce Input Ripple Voltage . To reduce the amount of ripple current fed back to the input supply (input reflected-ripple current), an external input filter can be added. Up to 10 µF of ceramic capacitance (C2) may be externally connected to the input of the SIP, provided the source inductance (LSOURCE) is less than 1 µH (see Figure 17). To further reduce the input reflected-ripple current, a filter inductor (LFILTER) can be connected between the supply and the external input capacitors (see Figure 18). As mentioned above, a 100 µF electrolytic capacitor (C1) should be added across the input of the SIP to ensure stability of the unit. The electrolytic capacitor should be selected for ESR and RMS current ratings to ensure safe operation in the case of a fault condition. Refer to Figure 19 for the appropriate electrolytic capacitor ratings. When using a tantalum input capacitor, take care not to exceed device power rating because of the capacitor’s failure mechanism (for example, a short circuit). The filter inductor should be rated to handle the maximum power SIP input current of 6.1 Adc. If the amount of input reflected-ripple current is unacceptable with an external L-C filter, more capacitance may be added across the input supply to form a C-L-C filter. For best results, the filter components should be mounted close to the power SIP. Note: Scope measurements should be made using a BNC socket, with a 47 µF tantalum capacitor .Position the load between 51 mm and 76 mm (2 in and 3 in) from the module Figure 15. Peak-to-Peak Output Ripple Measurement Test Setup. Note: All voltage measurements to be taken at the module terminals, as shown above. If sockets are used then Kelvin connections are required at the module terminals to avoid measurement errors due to socket contact resistance. Figure 16. Output Voltage and Efficiency Test Setup.

Setup with External Input Filter to Reduce Input Reflected-Ripple Current and Ensure Stability. Figure 19. Electrolytic Capacitor ESR and RMS Current Rating Data. Safety Considerations For safety-agency approval of the system in which the power module is used, the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standard, i.e., UL60950, CSA C22.2 No. 60950-00, and VDE 0805:2001-12 (IEC60950, 3rd Ed). For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV),the input must meet SELV requirements. The power module has ELV (extra-low voltage) outputs when all inputs are ELV. The input to these units is to be provided with a maximum 10A normal-blow fuse in the unearthed lead. If an input electrolytic capacitor is to be used, it should be selected using the design information found in the Design Considerations section. Lineage Power 9 Data Sheet October 14, 2009 Feature Descriptions Remote On/Off To turn the power SIP on and off, the user must supply a switch to control the voltage at the on/off terminal (Von/off). The switch can be an open collector pnp transistor connected between the on/off terminal and the VI terminal or its equivalent (see Figure 20). During a logic low when the ON/OFF pin is open, the power SIP is on and the maximum Von/off generated by the power SIP is 0.3 V. The maximum allowable leakage current of the switch when Von/off = 0.3 V and VI = 5.5 V (Vswitch = 5.2 V) is 50 µA. During a logic high, when Von/off = 2.8 V to 5.5 V, the power SIP is off and the maximum Ion/off is 10 mA. The switch should maintain a logic high while sourcing 10 mA. If not using the remote on/off feature, leave the ON/OFF pin open. The SIP has internal capacitance to reduce noise at the ON/ OFF pin. Additional capacitance is not generally needed and may degrade the start-up characteristics of the SIP. CAUTION: Never ground the on/off terminal. Grounding the on/off terminal disables an important safety feature and may damage the SIP or the customer system.

The test results for these configurations are displayed in Figures 21 and 22. Figure 21. NH020G Rtrim-down Test Results . Figure 20. Remote On/Off Implementation. Output Voltage Set-Point Adjustment (Trim) Output voltage set-point adjustment allows the output voltage set point to be increased or decreased by connecting an external resistor between the TRIM pin and either the VO pin (decrease output voltage) or GND pin (increase output voltage). The trim range for the NH020F is +10%, –16%. The trim range for the NH020G is ±10% of VO, nom. The trim range for SIPs that produce less than 2.5 VO is +20%, –0%. Connecting an external resistor (Rtrim-down) between the TRIM and VO pin decreases the output voltage set point as defined in the following equation. For the F (3.3 VO) SIP: Lineage Power Figure 22.

NH020F Rtrim-up Test Results . Overcurrent Protection Figure 23. NH020M Rtrim-up Test Results. To provide protection in a fault condition, the unit is equipped with internal overcurrent protection. The unit operates normally once the fault condition is removed. The power module will supply up to 350% of rated current for less than 1.25 seconds before it enters thermal shutdown. Overtemperature Protection To provide additional protection in a fault condition, the unit is equipped with a nonlatched thermal shutdown circuit. The shutdown circuit engages when Q1 or Q2 exceeds approximately 110 °C. The unit attempts to restart when Q1 or Q2 cool down and cycles on and off while the fault condition exists. Recovery from shutdown is accomplished when the cause of the overtemperature condition is removed. Figure 24. NH020Y Rtrim-up Test Results. Figure 25. NH020G Rtrim-up Test Results .

NH020M Power Dissipation vs. Output current. Note: Dimensions are in millimeters and (inches). Figure 27. Thermal Test Setup. Proper cooling can be verified by measuring the power SIP’s temperature at lead 7 of Q31 as shown in Figure 28. Figure 30. NH020Y Power Dissipation vs. Output Current. Figure 28. Temperature Measurement Location. The temperature at this location should not exceed 115 °C. The output power of the SIP should not exceed the rated power for the SIP as listed in the Ordering Information table. Convection Requirements for Cooling To predict the approximate cooling needed for the SIP, determine the power dissipated as heat by the unit for the particular application. Figures 29—32 show typical heat dissipation for the SIP over a range of output currents. Figure 31. NH020G Power Dissipation vs. Output Current.

With the known heat dissipation and a given local ambient temperature, the minimum airflow can be chosen from the derating curves in Figure 33. Figure 33. Power Derating vs. Local Ambient Temperature and Air Velocity. For example, if the unit dissipates 2.0 W of heat, the minimum airflow in an 80 °C environment is 1.0 m/s (200 ft./min.). Keep in mind that these derating curves are approximations of the ambient temperatures and airflows required to keep the power SIP temperature below its maximum rating. Once the SIP is assembled in the actual system, the SIP’s temperature should be checked as shown in Figure 28 to ensure it does not exceed 115 °C. Layout Considerations Copper paths must not be routed between pins 2 and 3 and pins 7 and 8. Lineage Power 13 Data Sheet October 14, 2009 Through-Hole Lead-Free Soldering Information The RoHS-compliant through-hole products use the SAC (Sn/Ag/Cu) Pb-free solder and RoHS-compliant components. They are designed to be processed through single or dual wave soldering machines. The pins have an RoHScompliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3°C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210°C. For Pb solder, the recommended pot temperature is 260°C, while the Pb-free solder pot is 270°C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process.

NH020-Series Power SIPs: 5 Vdc Input; 1.5 Vdc to 3.3 Vdc Output; 20 W Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to Tyco Electronics Board Mounted Power Modules: Soldering and Cleaning Application Note (AP01-056EPS). Solder Ball and Cleanliness Requirements The open frame (no case or potting) power module will meet the solder ball requirements per J-STD-001B. These requirements state that solder balls must neither be loose nor violate the power module minimum electrical spacing.
