Description

Austin MiniLynxTM 12V SIP (single-inline) power modules are non-isolated DC-DC converters that can deliver up to 3A of

output current with full load efficiency of 91% at 3.3V output. These modules provide precisely regulated output voltage

programmable via external resistor from 0.75Vdc to 5.5Vdc over a wide range of input voltage (VIN = 8.3 - 14V). Their open-

frame construction and small footprint enable designers to develop cost- and space-efficient solutions. In addition to

sequencing, standard features include remote On/Off, programmable output voltage and over current 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 6 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

Austin MiniLynxTM 12V 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 in the presence of inductive

traces that supply input voltage to the module.

In a typical application, a 22 µF low-ESR ceramic

capacitors will be sufficient to provide adequate ripple

voltage at the input of the module. To further minimize

ripple voltage at the input, additional ceramic

capacitors are recommended at the input of the

module. Figure 26 shows input ripple voltage (mVp-p)

for various outputs with a 10 µF or a 22µF input ceramic

capacitor at full load.

Design Considerations (continued)

Output Filtering

The Austin MiniLynxTM 12 V SIP 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,

Feature Description

Remote On/Off

Austin MiniLynxTM 12V SIP power modules feature an On/Off pin

for remote On/Off operation. Two On/Off logic options are

available in the Austin MiniLynxTM 12V series modules. Positive

Logic On/Off signal, device code suffix “4”, turns the module ON

during a logic High on the On/Off pin and turns the module OFF

during a logic Low. Negative logic On/Off signal, no device code

suffix, turns the module OFF during logic High and turns the

module ON during logic Low.

For positive logic modules, the circuit configuration for using the

On/Off pin is shown in Figure 27. 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.

For negative logic On/Off devices, the circuit configuration is

shown is Figure 28. The On/Off pin is pulled high with an

external pull-up resistor (typical Rpull-up = 68k, +/- 5%). 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 2.5 Vdc. 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.

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 Tref2, (see Figure 31) exceeds

140oC (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.

Output Voltage Programming

The output voltage of the Austin MiniLynxTM 12V can be

programmed to any voltage from 0.75Vdc to 5.5Vdc by

connecting a resistor (shown as Rtrim in Figure 29) between Trim

and GND pins of the module. Without an external resistor

between Trim and GND pins, the output of the module will be

0.7525Vdc. To calculate the value of the trim resistor, Rtrim for a

desired output voltage, use the following equation:

Using 1% tolerance trim resistor, set point tolerance of ±2% is

achieved as specified in the electrical specification. The POL

Programming Tool, available at www.gecriticalpower.com under

the Design Tools section, helps determine the required external

trim resistor needed for a specific output voltage.

Voltage Margining

Output voltage margining can be implemented in the

Austin MiniLynxTM 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 30 shows the circuit

configuration for output voltage margining. The POL

Programming Tool, available at

www.gecriticalpower.com under the Design Tools

section, also calculates the values of Rmargin-up and

Rmargin-down for a specific output voltage and % margin.

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 32. Note that the airflow is parallel

to the long axis of the module as shown in figure 31. The

derating data applies to airflow in either direction of the

module’s long axis.

Airflow

Figure 31. Tref Temperature measurement location.

The thermal reference point, Tref used in the specifications is

shown in Figure 32. 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.

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 by various module versus local ambient

temperature (TA) for natural convection and up to

0.5m/s (100 ft./min) are shown in the Characteristics

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 GE

technical representative for more details.
