CAUTION: This power module is not internally fused. An input line fuse must always be used.

This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of a complex 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 fastacting fuse with a maximum rating of 5 A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.

Design Considerations

Input Filtering

The Naos Raptor 3A module should be connected to a low ac-impedance source. 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 ceramic or polymer capacitors are recommended at the input of the module. Figure 46 shows the input ripple voltage for various output voltages at 3A of load current with 1x10 µF or 1x22 µF ceramic capacitors and an input of 12V.

Output Filtering

The Naos Raptor 3A 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 3A. For stable operation of the module, limit the capacitance to less than the maximum output capacitance as specified

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. 60950-1-03, 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.

The input to these units is to be provided with a fastacting fuse with a maximum rating of 5A in the positive input lead required, if the module is

. As an option to using a fuse, no fuse is

1. powered by a power source with current limit protection set point less than the recommended protection device value, and

2. the module is evaluated in the end-use equipment.

Feature Descriptions

Remote On/Off

The Naos Raptor 3A power modules feature an On/Off pin with positive logic for remote On/Off operation. If the On/Off pin is not being used, 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 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 average output current during hiccup is 10% I

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 130ºC is exceeded at the thermal reference point T 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.

Output Voltage Programming

The output voltage of the Naos Raptor 3A 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 Voltage Set Point Area plot in Fig. 49. The Upper Limit curve shows that for output voltages of 0.9V and lower, the input voltage must be lower than the maximum of 14V. The Lower Limit curve shows that for output voltages of 3.8V and higher, the input voltage needs to be larger than the minimum of 4.5V.

Monotonic Start-up and Shutdown

The Naos Raptor 3A modules have monotonic start-up and shutdown behavior for any combination of rated input voltage, output current and operating temperature range.

Tunable Loop

The Naos Raptor 3A modules have a new feature that optimizes transient response of the module called Tunable Loop 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 Loop be tuned externally by connecting a series R-C between the VOUT and TRIM pins of the module, as shown in Fig. 52. 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.

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 set-up is shown in Figure 53. The preferred airflow direction for the module is in Figure 54.

Wind Tunnel

Figure 53. Thermal Test Set-up.

The thermal reference point, T specifications of thermal derating curves is shown in Figure 54. For reliable operation this temperature should not exceed 120

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.

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 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. If additional information is needed, please consult with your Lineage Power technical representative for more details.
