Description

Austin SuperLynxTM II 12V SIP (single in-line package) power modules are non-isolated dc-dc converters that can deliver up

to 16A of output current with full load efficiency of 92% at 3.3V output. These modules provide a precisely regulated output

voltage programmable via an external resistor from 0.75Vdc to 5.0Vdc over a wide range of input voltage (VIN = 8.3 –

14Vdc). Austin SuperLynxTM II has a sequencing feature, EZ-SEQUENCETM that enable designers to implement various types

of output voltage sequencing when powering multiple modules on board. 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 fast-acting fuse with a maximum rating of 15 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 Austin SuperLynxTM II 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 a typical application, 6x47 µF low-ESR tantalum

capacitors (AVX part #: TPSE476M025R0100, 47µF

25V 100 mΩ ESR tantalum capacitor) will be

sufficient to provide adequate ripple voltage at the

input of the module. To further minimize ripple

voltage at the input, very low ESR ceramic

capacitors are recommended at the input of the

module. Figure 26 shows input ripple voltage (mVp-

p) for various outputs with 6x47 µF tantalum

capacitors and with 6x22 µF ceramic capacitor (TDK

part #: C4532X5R1C226M) at full load.

Design Considerations (continued)

Output Filtering

The Austin SuperLynxTM II 12V SIPmodule 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 6A in the

positive input lead.

Feature Descriptions

Remote On/Off

Austin SuperLynxTM II 12V SIP power modules feature an On/Off

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

available in the Austin SuperLynxTM II 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

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 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.

Output Voltage Programming

The output voltage of the Austin SuperLynxTM II 12V can be

programmed to any voltage from 0.75Vdc to 5.5Vdc by

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

Trim and GND pins of the module. Without an external resistor

between the 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:

By 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.

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 II 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.

Feature Descriptions (continued)

Voltage Sequencing

Austin SuperLynxTM II 12V series of modules include a

sequencing feature, EZ-SEQUENCETM that enables users to

implement various types of output voltage sequencing in their

applications. This is accomplished via an additional sequencing

pin. When not using the sequencing feature, either tie the SEQ

pin to VIN or leave it unconnected. SEQ pin not provided in -73Z

codes.

When an analog voltage is applied to the SEQ pin, the output

voltage tracks this voltage until the output reaches the set-point

voltage. The SEQ voltage must be set higher than the set-point

voltage of the module. The output voltage follows the voltage

on the SEQ pin on a one-to-one volt basis. By connecting

multiple modules together, customers can get multiple modules

to track their output voltages to the voltage applied on the SEQ

pin.

For proper voltage sequencing, first, input voltage is applied to

the module. The On/Off pin of the module is left unconnected (or

tied to GND for negative logic modules or tied to VIN for positive

logic modules) so that the module is ON by default. After

applying input voltage to the module, a minimum of 10msec

delay is required before applying voltage on the SEQ pin. During

this time, potential of 50mV (± 10 mV) is maintained on the SEQ

pin. After 10msec delay, an analog voltage is applied to the

SEQ pin and the output voltage of the module will track this

voltage on a one-to-one volt bases until output reaches the set-

point voltage. To initiate simultaneous shutdown of the

modules, the SEQ pin voltage is lowered in a controlled manner.

Output voltage of the modules tracks the voltages below their

set-point voltages on a one-to-one basis. A valid input voltage

must be maintained until the tracking and output voltages reach

ground potential to ensure a controlled shutdown of the

modules.

When using the EZ-SEQUENCETM feature to control start-up of

the module, pre-bias immunity feature during start-up is

disabled. The pre-bias immunity feature of the module relies on

the module being in the diode-mode during start-up. When

using the EZ-SEQUENCETM feature, modules goes through an

internal set-up time of 10msec, and will be in synchronous

rectification mode when voltage at the SEQ pin is applied. This

will result in sinking current in the module if pre-bias voltage is

present at the output of the module. When pre-bias immunity

during start-up is required, the EZ-SEQUENCETM feature must be

disabled. For additional guidelines on using EZ-SEQUENCETM

feature of Austin SuperLynxTM II 12V, contact GE technical

representative for preliminary application note on output

voltage sequencing using Austin Lynx II series.

Remote Sense

The Austin SuperLynxTM II 12V 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 31). 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 output pin of the

module.

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 33. Note that the airflow is parallel

to the long axis of the module as shown in figure 32. The

derating data applies to airflow in either direction of the

module’s long axis.

The thermal reference point, Tref 1 used in the specifications of

thermal derating curves is shown in Figure 32. For reliable

operation this temperature should not exceed 125oC.

The output power of the module should not exceed the rated

power of the module (Vo,set x Io,max).

Process For Open-Frame Board-Mounted Power Modules” for a

detailed discussion of thermal aspects including maximum

device temperatures.

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.
