Description
Austin LynxTM SIP power modules are non-isolated dc-dc converters that can deliver up to 10A of output current with full load efficiency of 95% at 3.3V output. These modules provide a precisely regulated output voltage programmable via an external resistor from 0.75Vdc to 3.63Vdc over a wide range of input voltage (VIN = 3.0 - 5.5Vdc). Their open-frame construction and small footprint enable designers to develop cost- and space-efficient solutions.

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 15A, time-delay fuse (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
Austin LynxTM SIP module should be connected to a low-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 polymer and ceramic capacitors are recommended at the input of the module. Figure 27 shows input ripple voltage (mVp-p) for various outputs with 1x150 F polymer capacitors (Panasonic p/n: EEFUE0J151R, Sanyo p/n: 6TPE150M) in parallel with 1 x 47 F ceramic capacitor (Panasonic p/n: ECJ-5YB0J476M, Taiyo- Yuden p/n: CEJMK432BJ476MMT) at full load.

Design Considerations (continued)
Output Filtering
The Austin LynxTM SIP module is designed for low output ripple voltage and will meet the maximum output ripple specification with 1 F ceramic and 10 F tantalum capacitors at the output of the module. 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 polymer and ceramic capacitors 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.
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 15A in the positive input lead.

Austin LynxTM SIP Non-isolated Power Modules, Programmable: 3.0Vdc - 5.5Vdc input; 0.75 to 3.63Vdc Output; 10A Output Current
The output voltage of the Austin LynxTM SIP can be programmed to any voltage from 0.75 Vdc to 3.3 Vdc by connecting a single resistor (shown as Rtrim in Figure 31) between the TRIM and GND pins of the module. Without an external resistor between the TRIM pin and the ground, the output voltage of the module is 0.7525 Vdc. To calculate the value of the resistor Rtrim for a particular output voltage Vo, use the following equation:
Feature Description
Remote On/Off
The Austin LynxTM power modules feature an an On/Off pin for remote On/Off operation. The On/Off pin is pulled high with an external pull-up resistor (typical Rpull-up = 68k, 5%) as shown in Fig. 28. When transistor Q1 is in the Off state, logic High is applied to the On/Off pin and the power module is Off. The minimum On/off voltage for logic High on the On/Off pin is 1.5Vdc. To turn the module ON, logic Low is applied to the On/Off pin by turning ON Q1. When not using the negative logic On/Off, leave the pin unconnected or tie to GND.

For example, to program the output voltage of the TM Austin Lynx module to 1.8 Vdc, Rtrim is calculated is follows:

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 3A.

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.
Overtemperature Protection
To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will shutdown if the thermal reference point Tref, exceeds 125oC (typical), but the thermal shutdown is not intended as a guarantee that the unit will survive temperatures beyond its rating. The module will automatically restarts after it cools down. By using a 1% tolerance trim resistor, set point tolerance of 2% is achieved as specified in the electrical specifications. The POL Programming Tool, available at www.lineagepower.com under the Design Tools section, helps determine the required external trim resistor needed for a specific output voltage

Feature Descriptions (continued)
The amount of power delivered by the module is defined as the voltage at the output terminals multiplied by the output current. When using the trim feature, the output voltage of the module can be increased, which at the same output current would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Pmax = Vo,set x Io,max).
(Vo x Io). When using Remote Sense, the output voltage of the module can increase, which if the same output is maintained, increases the power output by the module. Make sure that the maximum output power of the module remains at or below the maximum rated power. When the Remote Sense feature is not being used, leave the Remote Sense pin unconnected.

Voltage Margining
Output voltage margining can be implemented in the TM Austin Lynx modules by connecting a resistor, Rmarginup, from the Trim pin to the ground pin for margining-up the output voltage and by connecting a resistor, Rmargindown, from the Trim pin to the Output pin for marginingdown. Figure 32 shows the circuit configuration for output voltage margining. The POL Programming Tool, available at www.lineagepower.com under the Design Tools section, also calculates the values of Rmargin-up and Rmargin-down for a specific output voltage and % margin.

Remote Sense
The Austin LynxTM SIP power modules have a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage at the Remote Sense pin (See Figure 33). The voltage between the Sense pin and Vo pin must not exceed 0.5V. The amount of power delivered by the module is defined as the output voltage multiplied by the output current

Heat Transfer via Convection
Increased airflow over the module enhances the heat transfer via convection. Thermal derating curves showing the maximum output current that can be delivered at different local ambient temperature (TA) for airflow conditions ranging from natural convection and up to 2m/s (400 ft./min) are shown in the Characteristics Curves section.
Thermal Considerations
The power modules operate in a variety of thermal environments; however, sufficient cooling should always 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 34. Note that the airflow is parallel to the long axis of the module as shown in Figure 35. The derating data applies to airflow in either direction of the module's long axis.

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

Figure 35. Thermal Test Set-up. The thermal reference point, Tref used in the specifications is shown in Figure 34. For reliable o operation this temperature should not exceed 125 C. 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.
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 Lineage Power technical representative for more details.
