A highly inductive source can affect the stability of the module. An input capacitance must be placed directly adjacent to the input pin of the module, to minimize input ripple voltage and ensure module stability. LTEST VIN(+) BATTERY 1H CIN CS 1000F Electrolytic To minimize input voltage ripple, low-ESR ceramic or polymer capacitors are recommended at the input of the module.

Output Filtering VO COM 140 Rdistribution VO VIN Input Filtering Input Ripple Voltage (mVp-p) TO OSCILLOSCOPE x 100 % The Naos Raptor 6A modules are designed for low output ripple voltage and will meet the maximum output ripple specification with no external capacitors. However, additional output filtering may be required by the system designer for a number of reasons. First, there may be a need to further reduce the output ripple and noise of the module. Second, the dynamic response characteristics may need to be customized to a particular load step change. To reduce the output ripple and improve the dynamic response to a step load change, additional capacitance at the output can be used. Low ESR ceramic and polymer are recommended to improve the dynamic response of the module. Figure 47 provides output ripple information for different external capacitance values at various Vo and for a load current of 6A. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified in the electrical specification table. Optimal performance of the module can be achieved by using the Tunable LoopTM feature described later in this data sheet. (c)2016 General Electric Company. All rights reserved.

Safety Considerations 10K ON/OFF 2.2K For safety agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards, i.e., UL 60950-1, CSA C22.2 No. 60950-1-03, and VDE 0850:2001-12 (EN60950-1) Licensed. 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 extra-low voltage (ELV) outputs when all inputs are ELV. An input fuse for the module is recommended. Due to the wide input voltage and output voltage ranges of the module, different fuse ratings are recommended as shown in Table 1. These are suggested "maximum" fuse ratings. However, for optimum circuit protection, the fuse value should not be any larger than required in the end application. As an option to using a fuse, no fuse is required, if the module is 1. powered by a power source with current limit protection set point less than the protection device value listed in Table 1, and 2. the module is evaluated in the end-use equipment.

Remote On/Off Implementation. Resistor R1 is absent in the -49Z option module. Overcurrent Protection To provide protection in a fault (output overload) condition, the unit is equipped with internal current-limiting circuitry and can endure current limiting continuously. At the point of current-limit inception, the unit enters hiccup mode. The unit operates normally once the output current is brought back into its specified range. The average output current during hiccup is 10% IO, max. Overtemperature Protection To provide protection in a fault condition, these modules are equipped with a thermal shutdown circuit. The unit will shut down if the overtemperature threshold of 130C is exceeded at the thermal reference point Tref. The thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. Once the unit goes into thermal shutdown it will then wait to cool before attempting to restart. Input Undervoltage Lockout At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold. Feature Descriptions (continued) Output Voltage Programming The output voltage of the Naos Raptor 6A module can be programmed to any voltage from 0.59dc to 6Vdc by connecting a resistor between the Trim+ and GND pins of the module. Certain restrictions apply on the output voltage set point depending on the input voltage. These are shown in the Output Voltage vs. Input December 6, 2019 (c)2016 General Electric Company.

Output Voltage vs. Input Voltage Set Point Area plot showing limits where the output voltage can be set for different input voltages. Without an external resistor between Trim+ and GND pins, the output of the module will be 0.59Vdc. To calculate the value of the trim resistor, Rtrim for a desired output voltage, use the following equation: Rtrim 1.182 Vo 0.591 By using a 0.5% tolerance trim resistor with a TC of 25ppm, a set point tolerance of 1.5% can be achieved as specified in the electrical specification.

Figure 50. Circuit configuration for programming output voltage using an external resistor. Voltage Margining Output voltage margining can be implemented in the Naos Raptor 6A modules by connecting a resistor, Rmargin-up, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargin-down, from the Trim pin to output pin for margining-down. Figure 51 shows the circuit configuration for output voltage margining. The POL Programming Tool, available at www.gecriticalpower.com under the Design Tools section, also calculates the values of Rmargin-up and Rmargin-down for a specific output voltage and % margin.

Tunable LoopTM The Naos Raptor 6A modules have a new feature that optimizes transient response of the module called Tunable LoopTM. External capacitors are usually added to improve output voltage transient response due to load current changes. Sensitive loads may also require additional output capacitance to reduce output ripple and noise. Adding external capacitance however affects the voltage control loop of the module, typically causing the loop to slow down with sluggish response. Larger values of external capacitance could also cause the module to become unstable. 5V 3.3V 2.5V 1.8V 1.2V 0.69V RTUNE 100 75 47 47 47 47 CTUNE 12nF 27nF 39nF 100nF 220nF 330nF V 81mV 57mV 43mV 27mV 24mV 11mV Table 4.

This R-C allows the user to externally adjust the voltage loop feedback compensation of the module to match the filter network connected to the output of the module. Recommended values of RTUNE and CTUNE are given in Tables 3 and 4. Table 3 lists recommended values of RTUNE and CTUNE in order to meet 2% output voltage deviation limits for some common output voltages in the presence of a 3A to 6A step change (50% of full load), with an input voltage of 12V. Table 4 shows the recommended values of RTUNE and CTUNE for different values of ceramic output capacitors up to 1000uF, again for an input voltage of 12V. The value of RTUNE should never be lower than the values shown in Tables 3 and 4. Please contact your GE technical representative to obtain more details of this feature as well as for guidelines on how to select the right value of external R-C to tune the module for best transient performance and stable operation for other output capacitance values.

Page 15 GE Data Sheet Naos Raptor 6A: Non-Isolated DC-DC Power Modules 4.5Vdc -14Vdc input; 0.59Vdc to 6Vdc output; 6A Output Current Thermal Considerations Power modules operate in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. . The test setup is shown in Figure 53. The preferred airflow direction for the module is in Figure 54. Wind Tunnel Power Module 76.2 [3.0] 7.24 [0.285] Figure 54. Tref Temperature measurement location. Post solder Cleaning and Drying Considerations 50.8 [2.00] PWBs Airflow Direction Probe Location for measuring airflow and ambient temperature Air Flow Figure 53. Thermal Test Set-up. 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 Board Mounted Power Modules: Soldering and Cleaning Application Note. 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 RoHS-compliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process. If additional information is needed, please consult with your GE technical representative for more details. The thermal reference point, Tref used in the specifications of thermal derating curves is shown in Figure 54. For reliable operation this temperature should not exceed 120C. The output power of the module should not exceed the rated power of the module (Vo,set x Io,max). Please refer to the Application Note "Thermal Characterization Process For Open-Frame Board-Mounted Power Modules" for a detailed discussion of thermal aspects including maximum device temperatures December 6, 2019 (c)2016 General Electric Company.
