Description
TM
The 9-36V ProLynx series of power modules are non-isolated dc-dc converters that can deliver up to 3A 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 overtemperature 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.

TM
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 6 and 7
provides 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.

Ripple(mVp-p)
The 9-36V ProLynx modules are designed for low
output ripple voltage and will meet the maximum output
ripple specification with 0.1 µF ceramic and 10 µF
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.

Safety Considerations
For safety agency approval the power module must be
installed in compliance with the spacing and separation

Feature Descriptions
MODULE
Remote Enable
D2
TM
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. If the
On/Off pin is left floating the module will be in the ON
state.
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
shutdown if the overtemperature threshold of 130oC 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.

Data Sheet
October 17, 2011
Once the unit goes into thermal shutdown it will then
wait to cool before attempting to restart.
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.
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 under
voltage lockout turn-on threshold.
Output Voltage Programming
TM
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. 9. 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:
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
will not exceed 0.5V.

9-36V ProLynxTM: Non-isolated DC-DC Power Modules
9 – 36Vdc input; 3Vdc to 18Vdc output; 3A to 1.5A output current
Tunable LoopTM
The 9-36V ProLynxTM modules have a new feature that
optimizes transient response of the module called
TM
Tunable Loop .
External capacitors are usually added to the output of
the module for two reasons: to reduce output ripple and
noise (see Figures 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
TM
Loop 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 100μF 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.
Please contact your Lineage Power technical
representative to obtain more details of this feature as
well as for guidelines on how to select the right value of
external R-C to tune the module for best transient
performance and stable operation for other output
capacitance values or input voltages other than
12V/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
exceed 130°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.

Surface Mount Information
Pick and Place
The 9-36V ProLynxTM 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
o
temperatures of up to 300 C. The label also carries
product information such as product code, serial
number and the location of manufacture.
Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Variables such as
nozzle size, tip style, vacuum pressure and placement
speed should be considered to optimize this process.
The minimum recommended inside nozzle diameter
for reliable operation is 3mm. The maximum nozzle
outer diameter, which will safely fit within the allowable
component spacing, is 7 mm.
Bottom Side / First Side Assembly
This module is not recommended for assembly on the
bottom side of a customer board. If such an assembly
is attempted, components may fall off the module
during the second reflow process.
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.
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.
For questions regarding Land grid array(LGA)
soldering, solder volume; please contact Lineage
Power for special manufacturing process instructions.
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).
