## **Description** 

Austin SuperLynx[TM] SMT (surface mount technology) power modules are non-isolated dc-dc converters that can deliver up to 16A of output current with full load efficiency of 95% at 3.3V output.  These modules provide a precisely regulated output voltage programmable via 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.  Standard features include remote On/Off, remote sense, programmable output voltage, overcurrent and overtemperature protection.

## **Absolute Maximum Ratings** 

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only, functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.

## **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 20A (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 Austin SuperLynx[TM] SMT 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 26 shows the input ripple voltage (mVpp) for various outputs with 1x150 µF polymer capacitors (Panasonic p/n: EEFUE0J151R, Sanyo p/n: 6TPE150M) in parallel with 1 x 47 µF ceramic capacitor (Panasonic p/n: ECJ-5YB0J476M, Taiyo- Yuden p/n: 

CEJMK432BJ476MMT) at full load.   Figure 27 shows the input ripple with 2x150 µF polymer capacitors in parallel with 2 x 47 µF ceramic capacitor at full load.

**Data Sheet October 2, 2009** 

## **Design Considerations** (continued) 

## **Output Filtering** 

The Austin SuperLynx[TM] SMT module is designed for low output ripple voltage and will meet the maximum output ripple specification with 1 µF ceramic and 10 µF 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 20A in the positive input lead.

**Data Sheet October 2, 2009** 

## **Feature Description** 

## **Remote On/Off** 

The Austin SuperLynx[TM] SMT power modules feature an On/Off pin for remote On/Off operation of the module. The circuit configuration for using the On/Off pin is shown in Figure 28.  The On/Off pin is an open collector/drain logic input signal (Von/Off) that is referenced to ground. During a logic-high (On/Off pin is pulled high internal to the module) when the transistor Q1 is in the Off state, the power module is ON.  Maximum allowable leakage current of the transistor when Von/off = VIN,max is 10µA. Applying a logic-low when the transistor Q1 is turned-On, the power module is OFF.  During this state VOn/Off must be less than 0.3V.  When not using positive logic On/off pin, leave the pin unconnected or tie to VIN.

**Figure 28.  Remote On/Off Implementation.** 

## **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 3.5A. 

## **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 over temperature protection in a fault condition, the unit relies upon the thermal protection feature of the controller IC.   The unit will shutdown if the thermal reference point Tref, exceeds 125[o] C (typical), but the thermal shutdown is not intended as a guarantee that 

the unit will survive temperatures beyond its rating.  The module will automatically restart after it cools down. 

## **Output Voltage Programming** 

The output voltage of the Austin SuperLynx[TM] SMT can be programmed to any voltage from 0.75 Vdc  to 3.63 Vdc by connecting a single resistor (shown as Rtrim in Figure 29) between the TRIM and GND pins of the module.  Without an external resistor between 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: 

**==> picture [120 x 24] intentionally omitted <==**

For example, to program the output voltage of the Austin SuperLynx[TM ] module to 1.8 Vdc, _Rtrim_ is calculated is follows: 

**==> picture [201 x 162] intentionally omitted <==**

**----- Start of picture text -----**<br>

**Figure 29.  Circuit configuration for programming output voltage using an external resistor.** 

The Austin SuperLynx[TM] can also be programmed by applying a voltage between the TRIM and the GND pins (Figure 30).   The following equation can be used to determine the value of _Vtrim_ needed to obtain a desired output voltage Vo: 

_Vtrim_ = (7.0 − .01698×{ _Vo_ − .07525}) 

For example, to program the output voltage of a SuperLynx[TM] module to 3.3 Vdc, _Vtrim_ is calculated as follows: 

_Vtrim_ = (7.0 − .01698×{3.3 − .07525}) _Vtrim_ = .02670 _V_

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). 

## **Voltage Margining** 

Output voltage margining can be implemented in the Austin SuperLynx[TM] 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 the Output pin for margining-down.  Figure 31 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.

## **Feature Descriptions** (continued) 

## **Remote Sense** 

The Austin SuperLynx[TM] SMT 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 32).  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 (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, connect the Remote Sense pin to the output pin.

## **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 34.  Note that the airflow is parallel to the short axis of the module as shown in figure 33.  The derating data applies to airflow in either direction of the module’s short axis.

## **Heat Transfer via Convection** 

Increased airflow over the module enhances the heat transfer via convection.

## **Surface Mount Information** 

## **Pick and Place** 

The Austin SuperLynx[TM] SMT modules use an open frame construction and are designed for a fully automated assembly process.  The modules are fitted with a label designed to provide a large surface area for pick and place operations.  The label meets all the requirements for surface mount processing, as well as safety standards, and is able to withstand reflow temperatures of up to 300[o] C.  The label also carries product information such as product code, serial number and the location of manufacture. 

## **Reflow Soldering Information** 

The Austin SuperLynx[TM] SMT power modules are large mass, low thermal resistance devices and typically heat up slower than other SMT components. It is recommended that the customer review data sheets in order to customize the solder reflow profile for each application board assembly.  The following instructions must be observed when soldering these units.  Failure to observe these instructions may result in the failure of or cause damage to the modules, and can adversely affect long-term reliability. 

Typically, the eutectic solder melts at 183[o] C, wets the land, and subsequently wicks the device connection. Sufficient time must be allowed to fuse the plating on the connection to ensure a reliable solder joint.  There are several types of SMT reflow technologies currently used in the industry.  These surface mount power modules can be reliably soldered using natural forced convection, IR (radiant infrared), or a combination of convection/IR.  For reliable soldering the solder reflow profile should be established by accurately measuring the modules pin temperatures. 

**Figure 35.  Pick and Place Location.** 

## **Nozzle Recommendations** 

The module weight has been kept to a minimum by using open frame construction.  Even so, these modules have a relatively large mass when compared to conventional SMT components.  Variables such as nozzle size, tip style, vacuum pressure and placement speed should be considered to optimize this process. The minimum recommended nozzle diameter for reliable operation is 6mm. The maximum nozzle outer diameter, which will safely fit within the allowable component spacing, is 9 mm. 

Oblong or oval nozzles up to 11 x 9 mm may also be used within the space available. 

## **Figure 36.  Reflow Profile.** 

An example of a reflow profile (using 63/37 solder) for the Austin SuperLynx[TM ] SMT power module is : 

- Pre-heating zone: room temperature to 183[o] C (2.0 to 4.0 minutes maximum) 

- Initial ramp rate < 2.5[o] C per second 

- Soaking Zone: 155[o] C to 183[o] C – 60 to 90 seconds typical (2.0 minutes maximum) 

- Reflow zone ramp rate:1.3[o] C to 1.6[o] C per second 

- • Reflow zone: 210[o] C to 235[o] C peak temperature – 30 to 60 seconds (90 seconds maximum

## **Surface Mount Information** (continued) 

## **Lead Free Soldering** 

The –Z version Austin SuperLynx SMT modules are lead-free (Pb-free) and RoHS compliant and are both forward and backward compatible in a Pb-free and a SnPb 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. 

## **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. 37. 

## **MSL Rating** 

The Austin SuperLynx SMT modules have a MSL rating of 1. 

## **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 package is broken, the floor life of the product at conditions of ≤ 30°C and 60% relative humidity varies according to the MSL rating (see J-STD-033A).  The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions:  < 40° C, < 90% relative humidity. 

## **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).
