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. To minimize input voltage ripple, low-ESR polymer and ceramic capacitors are recommended at the input of the module. Figure 40 shows the input ripple voltage for various output voltages at 60A of load current with 2x22 µF or 4x22 µF ceramic capacitors and an input of 12V.

IIN x 100 % The Naos Raptor 60A 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. 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 11 Data Sheet December 6, 2010 TM the Tunable Loop data sheet. Naos Raptor 60A: Non Isolated Power Modules 5 – 13.8Vdc input; 0.6Vdc to 5.0Vdc Output; 60A output current feature described later in this Remote On/Off Safety Considerations 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. 60950-103, 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.

If not using the On/Off pin, leave the pin open (the module will be ON, except for the -49 option modules where leaving the pin open will cause the module to remain OFF). The On/Off signal (VOn/Off) is referenced to ground. During a Logic High on the On/Off pin, the module remains ON. During Logic-Low, the module is turned OFF.

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 typical average output current during hiccup is 10% of Io,max. Over Temperature Protection To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shut down if the overtemperature threshold of 135ºC is exceeded at the thermal reference point Tred. 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, module operation is disabled. The module will begin to operate at an input voltage above the undervoltage lockout turn-on threshold.

PwGood is a power good signal implemented with an open-collector output to indicate that the output voltage is within the regulation limits of the power module. The PwGood signal will be de-asserted to a low state If any condition such as over-temperature, over-current, or over-voltage occurs which would result in the output voltage going out of range.

Without an external resistor between Trim + and Trim - pins, the output of the module will be 0.6Vdc. To calculate the value of the trim resistor, Rtrim for a desired output voltage, use the following equation: The Naos Raptor 60A modules have monotonic startup and shutdown behavior for any combination of rated input voltage, output current and operating temperature range. Rtrim = 1.2 kΩ (Vo − 0.6) Rtrim is the external resistor in kΩ Vo is the desired output voltage Table 2 provides Rtrim values required for some common output voltages. By using a ±0.1% tolerance trim resistor with a TC of ±25ppm, a set point tolerance of ±0.8% can be achieved as specified in the electrical specification.

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. To use the additional external capacitors in an optimal manner, the Tunable LoopTM feature allows the loop to be tuned externally by connecting a series R-C between the SENSE and TRIM pins of the module, as shown in Fig. 43. 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 30A to 60A 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 1880 µF, 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 Lineage Power 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.

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 44. The derating data applies to airflow in either direction of the module’s axis. The thermal reference points, Tref1 and Tref2 used in the specifications are shown in Figure 45. For reliable operation this temperatures should not exceed 120ºC. 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 BoardMounted Power Modules” for a detailed discussion of thermal aspects including maximum device temperatures.

Thermal derating curves showing the maximum output current that can be delivered at different local ambient temperatures (TA) for airflow conditions ranging from natural convection and up to 2m/s (400 ft./min) are shown in the Characteristics Curves section. 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 the 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 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.
