Description

Austin SuperLynxTM 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.

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 fast-acting 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 SuperLynxTM 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 (mVp-p) 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.

Design Considerations (continued)

Output Filtering

The Austin SuperLynxTM 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 ANSI/UL 62368-1

and CAN/CSA C22.2 No. 62368-1 Recognized, DIN VDE 0868-

1/A11:2017 (EN62368-1:2014/A11:2017)

For the converter output to be considered meeting the

requirements of safety extra-low voltage (SELV) or ES1, the input

must meet SELV/ES1 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 fast-acting fuse

with a maximum rating of 20A in the positive input lead.

Feature Description

Remote On/Off

The Austin SuperLynxTM 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.

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 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 restart after it

cools down.

Output Voltage Programming

The output voltage of the Austin SuperLynxTM 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:

By using a 1% tolerance trim resistor, set point tolerance of ±2%

is achieved as specified in the electrical specification. The POL

Programming Tool, available at Go.ABB/Industrial under the

Design Tools section, helps determine the required external trim

resistor needed for a specific output voltage.

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

SuperLynxTM 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 Go.ABB/Industrial 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 GE technical representative for additional

details.

Remote Sense

The Austin SuperLynxTM 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.

Tref

Bottom View

Figure 33. Tref Temperature measurement location.

The thermal reference point, Tref used in the specifications is

shown in Figure 33. For reliable operation this temperature

should not exceed 115oC.

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 Board-Mounted Power Modules” for a

detailed discussion of thermal aspects including maximum

device temperatures.

Figure 34. Thermal Test Set-up.

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

temperatures (TA) for airflow conditions ranging from natural

convection and up to 2m/s (400 ft./min) are shown in the

Characteristics Curves section.

Layout Considerations

Copper paths must not be routed beneath the power module.

Surface Mount Information

Pick and Place

The Austin SuperLynxTM 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 300oC. The label also

carries product information such as product code, serial

number and the location of manufacture.

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.

Reflow Soldering Information

The Austin SuperLynxTM 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 183oC, 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 36. Reflow Profile.

An example of a reflow profile (using 63/37 solder) for the

Austin SuperLynxTM SMT power module is :

• Pre-heating zone: room temperature to 183oC (2.0 to 4.0

minutes maximum)

• Initial ramp rate < 2.5oC per second

• Soaking Zone: 155 oC to 183 oC – 60 to 90 seconds typical

(2.0 minutes maximum)

• Reflow zone ramp rate:1.3oC to 1.6oC per second

• Reflow zone: 210oC to 235oC 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 2a.

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
