Description
The 9-36V ProLynx series of power modules are non-isolated dc-dc converters that can deliver up to 5A of output current. These modules operate over an extra wide range of input voltage (VIN = 9Vdc - 36Vdc) and provide a precisely regulated output voltage from 3Vdc to 18Vdc, programmable via an external resistor. Two new features added with this family of products are the ability to externally tune the voltage control loop and a variable current limit inversely dependent on output voltage. Other features include remote On/Off, adjustable output voltage, over TM current and over temperature protection. The Tunable Loop , allows the user to optimize the dynamic response of the converter to match the load with reduced amount of output capacitance leading to savings on cost and PWB area and AutoLimit enables the module to deliver the max possible output power across the entire voltage range.

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 an integrated part of 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 fast-acting fuse with a maximum rating of 8 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 9-36V ProLynx 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, ceramic capacitors are recommended at the input of the module. Figure 28 shows the input ripple voltage for various output voltages at maximum load current with 2x10 F or 3x10 F ceramic capacitors and an input of 12V, while Fig. 29 shows the input ripple for an input voltage of 28V.

Output Filtering
The 9-36V ProLynx modules are designed for low output ripple voltage and will meet the maximum output ripple specification with 0.1 F ceramic and 10 F ceramic 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. Figures 30 and 31 provide output ripple information for different external capacitance values at various Vo and for full load currents. 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 TM achieved by using the Tunable Loop feature described later in this data sheet.

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 8A in the positive input lead.

Feature Descriptions
Remote Enable
The 9-36V ProLynx modules feature an On/Off pin for remote On/Off operation. Two On/Off logic options are available. In the Positive Logic On/Off option, (device code suffix "4" - see Ordering Information), the module turns ON during a logic High on the On/Off pin and turns OFF during a logic Low. With the Negative Logic On/Off option, (no device code suffix, see Ordering Information), the module turns OFF during logic High and ON during logic Low. The On/Off signal is always referenced to ground. For positive logic modules, the circuit configuration for using the On/Off pin is shown in Figure 32. When the external transistor Q1 is in the OFF state, the ON/OFF pin is pulled high and transistor Q2 is OFF leading to Q3 also being OFF which turns the module ON. The external resistor Rpullup (100k recommended) must be sized so that VON/OFF is never more than 12V when Q1 is OFF. In particular, if Vpullup is made the same as the input voltage Vin, the resistor Rpullup must be large enough so that VON/OFF is never more than 12V. For negative logic On/Off modules, the circuit configuration is shown in Fig. 33. When the external transistor Q1 is in the ON state, the ON/OFF pin is pulled low causing transistor Q2 to be OFF and the module to be turned ON. To turn the module OFF, Q1 is turned OFF, causing the ON/OFF pin to be pulled high turing Q2 ON and the module to be turned OFF. Leaving the On/Off pin floating will leave the module in an OFF state.

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 9-36V ProLynx modules employ an innovative, patent pending, `AutoLimit' capability. This results in automatic scaling of current limit with output voltage through an inverse relationship of the current limit threshold with the output voltage. This feature shown graphically in Fig. 34, allows higher output currents to be drawn from the module at lower output voltages thereby optimizing the power delivery capability of the module.

Over Temperature Protection
To provide protection in a fault condition, the unit is equipped with a thermal shutdown circuit. The unit will o shutdown if the overtemperature threshold of 130 C 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.
By using a 0.5% tolerance trim resistor with a TC of 100ppm, a set point tolerance of 1.5% can be achieved as specified in the electrical specification.
Remote Sense
The 9-36V ProLynxTM power modules have a Remote Sense feature to minimize the effects of distribution losses by regulating the voltage between the VS+ and Vo pin. The voltage between the VS+ pin and Vo pin should not exceed 0.5V.
Output Voltage Programming
The output voltage of the 9-36V ProLynx module can be programmed to any voltage from 3Vdc to 18Vdc 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. 35. Without an external resistor between Trim and GND pins, the output of the module will be 0.7Vdc. To calculate the value of the trim resistor, Rtrim for a desired output voltage, use the following equation:

Voltage Margining
Output voltage margining can be implemented in the 936V ProLynxTM 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 37 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 Please consult your local Lineage Power technical representative for additional details.

Tunable LoopTM
The 9-36V ProLynx modules have a new feature that optimizes transient response of the module called Tunable LoopTM. External capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise (see Figs 30 and 31) and to reduce output voltage deviations from the steady-state value in the presence of dynamic load current changes. 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. The Tunable LoopTM allows the user to externally adjust the voltage control loop to match the filter network connected to the output of the module. The Tunable LoopTM is implemented by connecting a series R-C between the SENSE and TRIM pins of the module, as shown in Fig. 38. This R-C allows the user to externally adjust the voltage loop feedback compensation of the module. Recommended values of RTUNE and CTUNE for different output capacitor combinations are given in Tables 2, 3 and 4. Tables 2 and 3 show recommended values of RTUNE and CTUNE for different values of ceramic output capacitors up to 100F that might be needed for an application to meet output ripple and noise requirements. Selecting RTUNE and CTUNE according to Tables 2 and 3 will ensure stable operation of the module In applications with tight output voltage limits in the presence of dynamic current loading, additional output capacitance will be required. Table 4 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 50% of full load step change with an input voltage of 12 or 28V.

Thermal Considerations
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 39. The preferred airflow direction for the module is in Figure 40. The derating data applies to airflow in either direction of the module's short axis. The thermal reference points, Tref used in the specifications are also shown in Figure 40. For reliable operation the temperatures at these points should not o exceed 115 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.

Lead Free Soldering
The 9-36V ProLynxTM modules are lead-free (Pb-free) and RoHS compliant and fully compatible in a Pb-free soldering process. Failure to observe the instructions below may result in the failure of or cause damage to the modules and can adversely affect long-term reliability.
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 (AN04-001).
Pb-free Reflow Profile
Power Systems will comply with J-STD-020 Rev. C (Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices) for both Pb-free solder profiles and MSL classification procedures. This standard provides a recommended forced-air-convection reflow profile based on the volume and thickness of the package (table 4-2). The suggested Pb-free solder paste is Sn/Ag/Cu (SAC). The recommended linear reflow profile using Sn/Ag/Cu solder is shown in Fig. 41. Soldering outside of the recommended profile requires testing to verify results and performance.
MSL Rating
The 9-36V ProLynxTM modules have a MSL rating of 2.
Storage and Handling
The recommended storage environment and handling procedures for moisture-sensitive surface mount packages is detailed in J-STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original
