Description

The 9-36V ProLynxTM series of power modules are non-isolated dc-dc converters that can deliver up to 5A of output current. These
modules operate over an extra wide range of input voltage (V
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
remote On/Off, adjustable output voltage, over current and over temperature protection. The Ruggedized version (-D) is capable of
operation up to 105°C and withstand high levels of shock and vibration. The Tunable Loop
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. The 9-36V
ProLynx can also be used for negative output voltage

loads through the use of a specific application schematic

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.

Design Considerations

Input Filtering

The 9-36V ProLynxTM module should be connected to a low
ac-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, ceramic capacitors are
recommended at the input of the module. Figure 28 shows
the input ripple voltage for various output voltages at
maximum load current with 2x10 µF or 3x10 µF ceramic
capacitors and an input of 12V, while Fig. 29 shows the input
ripple for an input voltage of 28V.

9Vdc –24Vdc input; -3.3Vdc to -18Vdc output; 5A to 0.7A Scaled output current

Output Filtering

The 9-36V ProLynxTM 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.

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 30 and 31 provide 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 achieved by using the
Tunable Loop

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 2nd, CSA C22.2 No. 60950-1-07, DIN EN 60950-1:2006
+ A11 (VDE0805 Teil 1 + A11):2009-11; EN 60950-1:2006 +
A11:2009-03.

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 fast-acting
fuse with a maximum rating of 8A in the positive input lead

Feature Descriptions

Remote Enable

The 9-36V ProLynxTM 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 R

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
turning Q2 ON and the module to be turned OFF. If the On/Off
pin is left floating, the module will be in the 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.

with a thermal shutdown circuit. The unit will shutdown if the

Once the unit goes into thermal shutdown it will then wait to
cool before attempting to restart.

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 undervoltage lockout
turn-on threshold.

Output Voltage Programming

The output voltage of the 9-36V ProLynxTM 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. 35.

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:

feature to minimize the effects of distribution losses by
regulating the voltage between the VS+ and Vo pin. The

Tunable Loop

TM

The 9-36V ProLynxTM modules have a new feature that
optimizes transient response of the module called Tunable

TM

.

Loop

External capacitors are usually added to the output of the
module for two reasons: to reduce output ripple and noise (see
Figs 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 output of the module. The Tunable Loop

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.

Shock and Vibration

The ruggedized (-D version) of the modules are designed to withstand elevated levels of shock and vibration to be able to operate
in harsh environments. The ruggedized modules have been successfully tested to the following conditions:

Non operating random vibration:

Random vibration tests conducted at 25C, 10 to 2000Hz, for 30 minutes each level, starting from 30Grms (Z axis) and up to
50Grms (Z axis). The units were then subjected to two more tests of 50Grms at 30 minutes each for a total of 90 minutes.

Operating shock to 40G per Mil Std. 810F, Method 516.4 Procedure I:

The modules were tested in opposing directions along each of three orthogonal axes, with waveform and amplitude of the shock
impulse characteristics as follows:

All shocks were half sine pulses, 11 milliseconds (ms) in duration in all 3 axes.

Units were tested to the Functional Shock Test of MIL-STD-810, Method 516.4, Procedure I - Figure 516.4-4. A shock magnitude of
40G was utilized. The operational units were subjected to three shocks in each direction along three axes for a total of eighteen
shocks.

Operating vibration per Mil Std 810F, Method 514.5 Procedure I:

The ruggedized (-D version) modules are designed and tested to vibration levels as outlined in MIL-STD-810F, Method 514.5, and
Procedure 1, using the Power Spectral Density (PSD) profiles as shown in Table 1 and Table 2 for all axes. Full compliance with
performance specifications was required during the performance test. No damage was allowed to the module and full
compliance to performance specifications was required when the endurance environment was removed. The module was tested
per MIL-STD-810, Method 514.5, Procedure I, for functional (performance) and endurance random vibration using the performance
and endurance levels shown in Table 5 and Table 6 for all axes. The performance test has been split, with one half accomplished
before the endurance test and one half after the endurance test (in each axis). The duration of the performance test was at least
16 minutes total per axis and at least 120 minutes total per axis for the endurance test. The endurance test period was 2 hours
minimum per axis.

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 temperatures of up to 300
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 GE for special manufacturing process
instructions.

MSL Rating

The 9-36V ProLynxTM 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 (AN04-001).

Negative Output Operation

Basic Scheme

The 9-36V ProLynxTM modules can also be used to create
negative output voltages from a positive input voltage.
Changing the input connection to as shown in Figure 44
converts the module from a synchronous buck converter to a
synchronous flyback converter

Figure 44. Schematic Connection of 5A ProLynx module for
negative output applications.

Remote Enable

Figures 33 and 34 still apply for remote On/Off operation.
However the On/Off threshold is now with respect to –Vout
instead of Ground. Before the module turns on, output is zero
so GND and –Vout are at the same potential. After the
module turns on, -Vout moves down and so will the ON/OFF
threshold. The following level shifting circuit can be used in
applications to limit exposure of the negative output voltage
to the On/Off circuitry.

Figure 45. On/Off Level Shifting Circuit for the 5A ProLynx
module for negative output applications.

Instead of directly turning Q1 On, the level shifting circuit is
used to turn Q1 On by first turning Q2 ON. When Q1 is in the
ON state, the ON/OFF pin is pulled low causing transistor Q5
to be OFF and the module to be turned ON. Both Q1 and Q2
are external transistors. To turn the module OFF, Q2 is turned

OFF, which turns Q1 OFF causing the ON/OFF pin to be pulled
high turning Q5 ON and the module to be turned OFF. If the
On/Off pin is left floating, the module will be in the OFF state.

Input Voltage Range

The 9-36V ProLynxTM modules when connected in a negative
output application will support a maximum input voltage
which is also a function of the output voltage. The sum of the
applied input voltage and magnitude of the output voltage
cannot exceed 36V. Vin(applied) +|Vout| ≤ 36 and Vout≤-3V. For
e.g. with a -12V output system the max input voltage that can
applied is only 24V. However, Figure 35 showing variation of
output voltage with Input Voltage should still be considered for
determining the required minimum input voltage.

Input voltage turn-on threshold remains the same as the
positive output connection. However the input turn-off
threshold tracks the output voltage and is reduced by the
same level. The listed input Turn-Off threshold of 7.35V when
applied to a -3.3Vout application will be measured as a 4.05V
(7.35V – 3.3V) threshold. Operating at input voltages below 9V
may cause the module to shut down earlier due to OCP
inception

Output Voltage Range

The 9-36V ProLynxTM modules will support the values of trim
resistors indicated in Table 1 to generate the same output
voltage, except with sign inversion. For an output voltage of
12V or higher the maximum input voltage will have to be
proportionally reduced from 24Vin so that the sum of the
magnitudes does not exceed 36V

Overcurrent Protection

The 9-36V ProLynx modules will automatically scale current
limit with output voltage through an inverse relationship of the
current limit threshold even in negative output voltage mode.
This feature is shown graphically in Fig. 46, allows higher
output currents to be drawn from the module at lower output
voltages thereby optimizing the power delivery capability of
the module.

capability at different output voltages.
